Abstract

Low Velocity Impact (LVI) experiments were performed on unidirectional laminate [0°]8 and cross-ply laminate [0°/90°]4 of e-glass/epoxy composite of thickness of 6.4 mm for incident energies 6.9 J, 9.48 J and 12.7 J. The energy, contact forces and displacement plots with respect to time are studied for drop test. The damage observed as back face signature on the back face of both cross-ply and unidirectional laminate are plotted. The composite was speckled randomly and the impact phenomenon was recorded by using a high-speed camera. The DIC data was analysed to obtain displacement and strains on the surface of the plate.
