Topic: Homogenization Methods: From Classical Models to Advanced Multiscale Techniques Homogenization techniques are fundamental approaches to predict the macroscopic behavior of heterogeneous materials based on their constituent properties and microscopic structures. These techniques primarily aim to derive overall material and structural properties from the characteristics of individual constituents. In most multiscale modeling frameworks, however, simultaneous interactions between various levels of materials is considered in the computational models.In this presentation, a brief review of the relatively extensive history of the homogenization theories from early models of simple Voigt (1928) and Reuss (1929) to more advanced formulations, including the Hashin-Shtrikman bounds (1963) and asymptotic homogenization (1978) will be discussed. While these methods effectively address periodic or presumed periodic media, stochastic homogenization (1979) has broadened the scope to include random materials. Furthermore, nonlinear homogenization also addresses complex behavior of materials such as plastic deformation and damage in which multiscale modeling would be necessary. In this area, with the rise of computational methods, the multiscale FEM (1997) and the generalized multiscale FEM (2009) offered more efficient multiscale tools. Recently, machine learning techniques have also been integrated into the homogenization to accelerate multiscale computations (2020) and predict effective material properties directly from data (2023). An overview of the possible future directions in the homogenization methods to further advancements in nonlinear, multiphysics systems through AI-driven approaches will be discussed. |

Topic: 4D printing of shape memory polymers through materials extrusion additive manufacturing 4D printing is a new emerging advance in the 3D printing area. The excess dimension refers to the intelligent function of the 4D printed part that can alter its shape over time by its dynamic capability. 3D printing can be combined with Smart Materials (SMs) specially Shape Memory Materials (SMMs) to make 4D printing for advanced applications such as self-assembly, self-adaptation, sensing, and actuating complex geometries and multi-material structures. In fact, 3D printing, smart materials and stimulation are the three main wings of 4D printing. Fused deposition modeling (FDM), which is used for printing thermoplastic polymers, is one of the easiest, most efficient, and cost-effective approaches. The most important advantage of the 3D printing technique is in removing the limitations of the design and construction of complex structures, as well as the production of personalized equipment, especially in the medical field. Smart materials (SM) refer to the class of materials that respond to the changes in their surroundings and environment. In general, they are categorized into seven classes in which the SMMs are the most widely used and considered. Shape memory polymers (SMPs) have been studied extensively as the most applicable group of SMMs due to their ease of process-ability and wide application. The most remarkable features can be included as low density, high strain records, fast recovery speed, adaptable properties (transition temperature), the programmability and controllability of recovery behavior, low cost, easy processing, and the ability to achieve biodegradability. Heat-activated SMPs are the most widely used and well-regarded subgroup of SMs, capable of recovering the original (permanent) shape from a deformed state as a temporary shape by heating stimulation. This ability, known as the shape memory effect (SME), is not an inherent property of polymers and often results from the combination of three major factors: morphology, molecular architecture, and deformation history.Programming includes three main stages of heating/loading, cooling/unloading and recovery, where the two main parameters of shape fixity and shape recovery are measured at the end of the loading and recovery stages. Programming and stimuli are the third wing of 4D printing, which will be possible with the addition of magnetic and electric fillers for indirect stimulation and activation. Magnetic-sensitive (magneto response) shape-memory composites have attracted the attention of many researchers in various fields, including medical applications, due to outstanding features such as remote activation capability. Iron oxide nanoparticles Fe3O4 are one of the most common nanoparticles that react to magnetic fields.Therefore, in order to use and expand 4D structures in industrial applications, the three sections of structure design, design of shape memory material, and programming and stimuli should be strengthened and a balance and harmony should be created between them. |

Topic: Impact Behaviour of Lightweight Smart Composites With the knowledge of composite materials from the last half century and its various applications in the industry from the last three decades, the science of these materials and structures in the construction of light weight structures and increasing the safe design capability for engineers due to the possibility of simultaneous design of materials and structures has gone gradually increased in such a way that scientists have gone towards the use of these light materials in special applications such as impact loading. With the understanding of smart materials and their unique features and the ability to make and use them in composite structures, practically new attitudes have been formed in the design, mechanics and also the behavior of these structures in different loads and their use in important applications. In this review research work, the behavior of smart composite lightweight structures under impact loading is investigated. In this research, after introducing composite materials and smart materials and how to combine these two together to achieve lightweight smart composite structures, the effect of various parameters on the behavior of these structures is investigated and discussed. Studying the integrity of the structure and their resistance against these loadings, as well as examining their failure behavior, helps to make the design of such structures more acceptable, reliable, operational, and practical for design engineers. In this research, the effect of one of the smart materials, i.e. shape memory alloys, has been used to improve the properties of laminated fiber composites under impact conditions. Also, on improving the behavior of the structure in impact, other smart technology is used with the name of self-healing composites. In this presentation, the processes, the materials, the tests, and the results and behavior of such structures will be examined. |

Topic: Multiscale Modelling of Fatigue of Metals Recently, Multiscale Materials Modelling (MMM) has grown in importance and simultaneously became a central idea in understanding present days’ complex and advanced materials. As a part of MMM, considerable emphasis has been put at our institute in developing numerical models for predicting also fatigue lifetime of metallic materials. At the microstructural level, the physically-based Tanaka-Mura model (TMM) has been extended to elevated temperature conditions and microstructural characteristics such as porosities, and proves to be a very promising model to estimate the number of cycles for a fatigue crack to be initiated. One of the parameters of the model is the critical resolved shear stress (CRSS) on a slip plane, which is of particular interest since it can be obtained by means of micro-pillar tests or alternatively by Molecular Dynamics simulations on the nano scale. Concerning the macro scale and long crack growth predictions, there exist numerous established models that produce acceptable results, e.g. the wellknown Paris law and its numerical realization. The present work comprises several fatigue problems of metals for which the modelling framework has been successfully applied, including the numerical determination of fatigue life (S-N, Wöhler) curves for materials and for components as well as elucidating the influence of the CRSS on these curves. This physically based multiscale approach presents a breakthrough in the field of fatigue research and opens the door to fast and inexpensive virtual materials development as well as fatigue resistant component design for fatigue application, e.g., under large deformation conditions. |

Topic: Additive Manufacturing: your Permission to Catch the Future through 3D Printing For decades, it has been like a dream in technology trend to reach out to development millstone of touching real 3D printed objects directly from the computer screens, the CAD models, instead of just getting satisfied by having only the dramatic phantoms on a paper sheet. Now, the dream is in reality world, for years, and is rising fast being considered a mature technology. One may comment on the statement that such technologies, Selective Laser Sintering SLS methods for instance, have been available for many years and nothing would be considered as an exciting matter with this. To response yes, 3D printing techniques have been developing during the years however, it is available in quiet wide range of accessibilities, in moderate to cheap cost and advanced technological specifications. Nowadays, selection list of 3D printers is in commercial products that can provide high output printing rate in very low resolution (< 20 micron) and using standard or functional materials which are emerging everyday by different producers all around the world. Among the other names DLP and mSLA printing technologies, due to versatility, rate of printing and lower cost of printing in addition to other economic aspects, have been developed widely and is being used for many different applications in research and industrial centers. Though, polymeric materials are definitely the major reason for diversity of 3D Printing technologies however, they have been and are being considered as the most practically important part of the successful printing in mSLA and DLP. The latter techniques build the 3D printed object directly from photosensitive mixture of polymeric materials or resins. By changing the resin properties, one can have 3D printed objects with different functionalities of desired application. High strength, high modulus, chemically resistive, high temperature, transparent, biocompatible, electrically conductive, high resolution, investable, flexible, transparent and many other properties are only examples of the properties that a printing can result in. The aim of the talk will be all around the mSLA and DLP printing techniques with cons and pros around the techniques and current applications in addition to prospects that are now open for scientists and engineers to define target research projects. |

Topic: On the long-term behavior of composite pipes Dictated by international rules and regulations, composite pipes are supposed to sustain their missions for 50 years as the service lifetime of the infrastructure industry. Therefore, composite pipes are required to be designed in accordance with the long-term design constraints as the most challenging design requirements. The long-term performance of a composite pipe is examined under two different expensive and cumbersome experimental programs for a period of more than two years. These experimental programs should be carried out for any new layup configuration as the approval of the pipe design configuration. The very long duration of the costly certification procedure is hindering industrial producers from developing new products. Thus, it is vital to predict the long-term behavior of composite pipes at early design stages and prior to mass production. Two computational modeling procedures are developed to predict the remaining properties of composite pipes for two different load cases of internal pressure and compressive transverse loading after 50 years. The developed modeling procedures require limited experimental data through short-term tests. Validated through an extensive experimental program on industrial-scale composite pipes, the developed modeling techniques are able to estimate the remaining properties of the pipes on a long-term basis with a very high level of accuracy. Moreover, the modeling procedure is extended to take into account the influence of water absorption, fulfilling the requirements of the normative standard for analyzing the long-term behavior under wet conditions. Despite the development of the sophisticated computational methods for estimating the long-term response of composite pipes, the conducting of qualification tests cannot be waived. Consequently, an alternative testing program is proposed to reduce the duration of the experimental program to three months as the final step. |
