- In this work, numerical investigation is performed to study the behaviour of a composite laminates and shell structure under low velocity impact. Woven fabric composite shell having different radius of curvature is considered, the present paper discusses on the effect of the ratio of radius to arc length on the central deflection for plate and spherical shell. A Varity of examples are presented to study the impact responses. The parameters included in this study are curvature of the shell, boundary condition and impact velocity.using the commercial finite element analysis software ANSYS/ LS-DYNA. Finite element simulation is performed to investigate the stress distribution during the impact. Comparison of plate and spherical shell structure are considered in this paper Numerical analysis has been done by creating program in analysis software ANSYS and different results are obtained. The outcomes of results are compared with results available in the literature.
