Investigation on Homogeneous Modeling of Gyroid Lattice Structures: Numerical Study in Static and Dynamic Conditions

The TPMS (triply periodic minimal surface) are receiving great attention for production of open cell scaffold structures, example in biomedical applications. In this paper stretch-dominated lattice structures have been considered. Gyroid made epoxy resin by DLP technology was analyzed. compression test results quasi-static (10 -3 s -1 ) and dynamic (4x10 2 conditions used to compute the macroscopic cellular material properties homogenization methods. Finally, order evaluate behaviour unit under multi-axial stress state, combined shear-compression tests carried out as well.
