Analysis of dynamic behavior of triply periodic minimal surface (TPMS) structures

This thesis investigates the dynamic behaviors of Triply Periodic Minimal Surface (TPMS) structures, focusing on lattice beams with Gyroid, Diamond, Primitive, and I-WP topologies, and their deformation, modal analysis, and critical buckling forces under various boundary conditions. TPMS structures have significant advantages such as high mechanical performance, lightness, and energy absorption. The objective of the study is to understand the effect of TPMS geometry and boundary conditions on the structures' natural frequencies, bending, and buckling forces. Using Simcenter 3D software, different boundary conditions were defined for each TPMS topology, and the natural frequencies, deformations, and buckling forces were calculated for each structure. The analysis demonstrates that TPMS geometry and the correct combination of boundary conditions play a critical role in minimizing resonance, deformation, and buckling risks. The study concludes that optimizing TPMS structures with appropriate boundary conditions can improve structural integrity and dynamic performance.
