| Abstract Scope |
The design, modeling and optimization of cellular materials for energy absorption remains one of the more challenging sub-domains within architected cellular and meta-materials for mechanical behavior. The work in this field is primarily of an empirical and experimental nature with most of it involving constant thickness cellular structures. This gap can be attributed to the modeling challenges associated with accurately representing the large deformations and contact seen in cellular materials subjected to very large compressive strains. This work addresses this gap by proposing, developing, implementing and validating a continuum shell based finite element model that enables the simulation of the behavior of variable thickness Schwarz-P TPMS cellular structures. Four different fields: two rational (linear gradient and failure band) and two stochastic, are implemented and studied, with all showing improvements over the uniform thickness baseline. |
