Hallquist, J O

A numerical procedure is presented for solving the finite-deformation dynamic contact-impact problems by the finite element method. After impact, penetration is precluded by constraint conditions that are imposed by a transformation of the generalized displacements in the equations of motion. Either friction or frictionless interface conditions can be assumed along the contact surface. Five numerical examples are provided to demonstrate the accuracy and the flexibility of the method. 35 figures, 3 tables.
