Abstract

This article aims to investigate the structural behavior of Ultra High Performance Epoxy Composite Plate subjected to velocity impact loading. Two types of material were utilized for the composite plate: epoxy, and UHPC. UHPC plate plays as a front layer to strengthen the energy absorption and protect the epoxy layer. The material model used to simulate the epoxy plate was verified by experimental results to prove its accuracy and efficiency. Impact loading was implemented in the Abaqus model by an impactor nose which has 25mm diameter. The projectile was assumed at the velocity of 120 m/s. The damage propagated due to the increment of the impact energy was estimated by the Johnson-Holmsquist concrete (JHC) material model in Abaqus. Maximum deflection, the kinetic energy versus internal energy were also investigated in the current article. Based on the obtained result, the Epoxy material combined with UHPC material was proved to be a potential application in impact resistance design.
