Oblique impacts of metallic plates in an elastic formulation

A previous work [1], in which the thickness of the colliding plates was assumed to be infinitely great and the velocity of the point of contact greater than the speed of sound c₁ in the matterial, represented one attempt to use linear elasticity theory in flash-welding problems. Oblique impact of metallic plates of finite thickness has been studied [2], the velocity V_c of the point of contact being assumed to be less than the velocity c₂ of transverse waves in the material. In this work, oblique impact of elastic plates with velocities V_c of the point of contact greater than the velocity of propagation c₂ of transverse waves will be considered.
