Low velocity impact on relatively thick rectangular plate under in-plane loads resting on pasternak elastic foundation

Rectangular plates, subjected to external in-plane loads, with different sizes, thickness variations and boundary conditions have undoubtedly been one of the key components in aerospace, civil, automotive, optical, electronic, mechanical, and shipbuilding industries. They may also be supported by an elastic foundation. These kinds of plates are mainly used in concrete roads, raft, and mat foundations of buildings and reinforced concrete pavements of airport runways. Abrate [1] implied that the first step for thorough understanding of impact event is choosing an appropriate model for prognosis force and displacement histories that involves the motion of the target, the motion of the projectile, and the local indentation in the contact zone. Hence many models have been proposed in the literature. These models can be classified into three categories: (1) energy-balance models that assume a quasi-static behavior of the structure; (2) spring-mass models that account for the dynamics of the structure in a
