Abstract

An efficient formulation for frictional contact/impact problems based on a newly developed decoupled point to segment gap vector projection model and employing the so-called arbitrary reference configuration formulation for finite elastic/inelastic deformation and the forward incremental displacement central difference time integration scheme for the equation of motion is developed. The resulting normal and tangential contact boundary formulations are easy to solve, and the contact constraints are satisfied exactly. The overall formulation is robust and efficient for the numerical simulation of finite deformation elastic/inelastic frictional contact/impact problems.
