Abstract

This study presents the peridynamics simulation of compression-after-impact (CAI) in two subsequent stages of impact and compressive type of loading. In the first stage, a transient analysis is performed that simulates the motion of a rigid impactor hitting a laminated specimen, leading to damage in the specimen. The simulation continues for additional time steps after the impactor rebounds from the specimen; subsequent impacts are not allowed. Once the transient effects in the impact problem dies out, the damaged specimen is subjected to compressive in-plane loading, resulting in further damage and eventual structural failure of the laminate.
