Abstract: To investigate the mechanical properties of alumina ceramic Triply Periodic Minimal Surface (TPMS) structures, this study adopts modeling and construction of solid plate structures as well as two typical TPMS structures (Gyroid and Schwartz). Through Abaqus finite element simulation, the influence of structure types on their elastic modulus, tensile strength, and specific strength is systematically analyzed. The results show that TPMS structures exhibit significant mechanical advantages compared with traditional solid structures. This study clarifies the influence laws of mechanical properties of alumina ceramic TPMS structures, verifies the accuracy of the numerical model, and provides theoretical basis and technical support for their optimized design and engineering applications in fields such as aerospace lightweight components and biomedical scaffolds.
