Compressive behavior of selective laser melting printed Gyroid structures under dynamic loading

The compressive behavior of a typical triply periodic minimal surface (TPMS) structure (Gyroid structure) fabricated by selective laser melting (SLM) is investigated experimentally and numerically under different loading rates. By using the digital imaging correlation (DIC) method, the deformation process is recorded to examine the deformation evolution in the specimens. The loading rate sensitivities of yield stress, plateau stress, and...
