Abstract
The gyroid based structure is a type of triply periodic minimal surface (TPMS), which nowadays can be realized by additive manufacturing techniques. This is a promising lightweight structure, that can be of great use in mitigating impact energy, when gyroid structures are used as kinetic energy absorbers. In this paper, a gyroid structure stands modeled via the finite element method. The gyroid is subjected to the impact of a dropping mass. The material was subjected to an extensive characterization based on digital image correlation. Johnson-Cook material parameters were obtained. The FE models were evaluated by comparing the force-displacement response to experimental impact tests. The FE models were able to represent the overall response of the gyroid under a different level of impact loadings.
