Dynamic Elastoplastic Interaction between an Impactor and a Spherical Shell

Dynamic axisymmetric elastoplastic interaction between a massive body and a simply supported, circular segment of a spherical shell is studied. The problem of determining the contactinteraction force is formulated for the case of spherical and conical bodies. A nonlinear integral equation is derived for various models of local plastic compression using the equations of equilibrium of a membrane spherical shell written in terms of radial displacement of the shell. Numerical results are presented graphically.
