Abstract

This paper investigates the low-velocity impact response of a glass fiber-reinforced polymer (GFRP) composite. A four-layered anisotropic bidirectional glass fiber composite laminate is modeled using HyperMesh. The thickness of each ply is considered as 0.5 mm, and the radius of the impactor is 10 mm. The oblique angle impact at 0°, 15°, 30°, and 45° (inclination of laminates with the horizontal plane) is simulated using LS-DYNA, which is a 3D commercially available software. A comparative study is carried out for energy absorption, stress generation, damage caused, and deflection of the laminate at 3 m/s impact velocity. The results of the mechanical testing simulations justified that the impact angle highly influences the impact response. Therefore, it may help in designing mechanical components that are exposed to oblique low-velocity impact (LVI) situations.
