This is a progress report on a finite element formulation of contact-impact problems in continuum mechanics. Several check problems are reported upon which employ the so-called Hertzian algorithm described in earlier work. The development of finite element models for nonlinear compressible, incompressible and nearly-imcompressible elastic bodies is described, and a detailed algorithm is presented for determining if, and where, contact has been made for the kinematically nonlinear case.
