“…A number of other studies have conducted FEA using simple elastic–perfectly plastic constitutive models to predict the elastic and yield properties of TPMS‐based lattices [5d,28a,39a,45b,58,72]. However, understanding the coupled material–topology–property relationship for large deformations requires the use of more complex constitutive models that can be calibrated based on the properties of the base materials.…”

In nature, cellular materials exhibit enhanced multifunctionalities driven mainly by their sophisticated topologies and length scales. These natural systems have inspired the development and expansion of synthetic architected materials for revolutionary applications. Consequently, both the design and synthesis techniques gained considerable attention and have massively progressed over the last few decades. Such materials with topology-controlled properties are commonly known as "metamaterials." Architected materials with topologies based on triply periodic minimal surfaces (TPMS) which are of particular interest have attracted much attention recently due to their mathematically controlled fascinating topologies and their exhibited physical and mechanical properties. Herein, the design, synthesis, and use of TPMS in the field of metamaterials and metacomposites for several applications are focused upon. The design process to create TPMS-based 3D lattices is summarized and the different manufacturing processes used to fabricate these lattices are highlighted. Herein, the materialtopology-mechanical properties relationship of different TPMS-based lattices that are investigated in the literature is discussed. A further objective is to highlight the applications where TPMS-based lattices or composites can be efficiently used as well as the research areas to be explored. development of macro/micro/nanomechanics-based constitutive models and computational tools that can be used effectively in guiding the design of advanced materials. He is particularly active in using digital design and 3D printing for creating multifunctional architected materials and composites for various applications.

“…Before fabricating the hybrid hydrogel systems, a finite volume method (FVM) simulation was carried out to investigate the effects of Pg-20-5 h hydrogel infiltration on the mechanical performance of the 3D printed scaffolds and probe the load-bearing behavior of the hybrid systems under uniaxial compression conditions. Quasi-static uniaxial compression simulations were performed in the z-axial direction via a commercial software package, GeoDect 24 .…”

The inability of damaged load-bearing cartilage to regenerate and self-repair remains a long-standing challenge in clinical settings. In the past, the use of PVA hydrogels as cartilage replacements has been explored; however, both pristine and annealed PVA are not ideal for load-bearing cartilage applications, and new materials with improved properties are highly desirable. In this work, we developed a novel hybrid hydrogel system consisting of glycerolmodified PVA hydrogel reinforced by a 3D printed PCL-graphene composite scaffold. The composition of the hydrogel within the hybrid material was optimized to achieve high water retention and enhanced stiffness. The hybrid hydrogel formed by reinforcement with a 3D printed PCL-graphene scaffold with optimized architecture demonstrated desirable mechanical properties (stiffness, toughness, and tribological properties) matching those of natural loadbearing cartilage. Our novel hydrogel system has also been designed to provide drug release and on-demand photothermal conversion functions and at the same time offers excellent biocompatibility with low cell adhesion. These promising properties may allow our unique hybrid hydrogel system to be used for potential applications, such as load-bearing cartilage repair/replacement, as well as targeting certain challenging clinical conditions, such as the treatment of severe arthritis.

“…They found that with the same structural parameter, Gyroid structures have the highest compression strength, whereas Neovius structures have the lowest compression strength. Zheng et al [35] carried out a systematic semi-theoretical study on Gyroid, Schwarz Primitive, IW, and iWP TPMS structures, analyzing the relation between the microstructure and macroscopic mechanical properties through numerical simulations. They found that Primitive structures exhibit stretch-dominated deformation mode, whereas the deformation of the others is bending-dominated.…”
