Influence of speed of soft body projectile on damage in bio-inspired helicoidal laminates using SPH-FEM model

Abstract

This study investigates the impact response of bio-inspired helicoidal laminated composite plates under soft body impacts using the SPH methodology in ABAQUS. Impacts at velocities of 50 m/s, 100 m/s, and 200 m/s are analyzed for different helicoidal schemes. The model is validated against existing literature, and damage is evaluated using the Hashin failure model. Helicoidal laminates exhibit less damage than cross-ply and quasi-isotropic laminates. Damage increases with impact velocity, becoming severe at 200 m/s, with significant vibrations. The study highlights the superior performance of helicoidal laminates under high-velocity impacts.
