Response of gyroid lattice structures to impact loads

This paper reports on a comprehensive investigation of gyroid lattice structures subject to impact loading. AlSi10Mg samples were manufactured using selective laser melting (SLM) and mechanically characterized Digital Image Correlation (DIC). Universal testing machines, drop weight rig, split pressure Hopkinson bar used characterize the aluminium alloy at strain rates ranging from, ??=10?3s?1 up 5500 s?1. Gyroid tested in drop-weight rig different conditions, where tests results validated by FE analysis. These tests, measurements, analysis enabled development modified isosurface equation, providing an opportunity investigate their response, wall thickness, unit cell size, curvature studied low-velocity conditions. The indicate that changes topology substantially affect its performance.
