Composite materials are widely used for engineering applications due to their unique features and special characteristics. A composite material is made from different components which own different mechanical and physical properties. This composite has an elevated and improved physical and mechanical properties compared to its individual components. When a composite material is used for a specific application, it can be exposed to different types of damages, mainly from impact. Therefore, it is important to investigate the composite behavior during impact loading. This research project aims to simulate the impact behavior of a composite material using the ABAQUS software. The S-glass/Polyester composite laminate plate is selected for simulation under three different impact energy by an impactor with drop heights of 0.5 m, 0.75 m and 1 m. This is to generate three different levels of impact velocity and hence impact energy on the composite plate. In this project, the ABAQUS Explicit with dynamic solver which is suitable for the impact problems is selected for simulation and the Hashin criterion is used to predict damage and failure behavior of the composite plate. The obtained results for three impact energy levels show that a higher impact energy results in a higher deflection of plate at its center, a higher von Mises stress and a higher Hashin damage value for the plate. The simulation results are also validated with corresponding experimental data from the literature and a reasonable agreement between the simulation results and experimental data is observed.
