In the present work, the dynamic response of polycarbonate plates subjected to the projectile impact in different velocities was investigated. The plates were modeled with dimensions 400mm × 400mm and the thickness was taken of 2mm. In addition, impact locations at plate center, 90mm and 180mm away from the center point were carried out by a spherical steel projectile. The numerical investigation of impact response of a polycarbonate plate is conducted by using LS-DYNA. Polycarbonate material behaves in an elastoplastic manner. Therefore, the plate was modeled using elastic-plastic material properties. A validation study was achieved by solving the impact response given in the literature and compared with the results. In numerical analysis, the plate was clamped at all edges and the impacting steel projectile was modeled as a rigid body. As a result, perforation and penetration behaviors of polycarbonate plates were investigated for different locations of the plates. In this way, maximum plastic strain, von Mises stresses, and energy absorbed by the plate were computed. The simulation results were evaluated and discussed in detail.
