摘要：
A contact finite element has been developed to solve elasto-plastic contact problems frequently encountered in metal forming processes. The element developed is based on the methodology originally used for solving elastic contact problems. It employs an interface spring algorithm that yields a symmetric type of elemental stiffness matrix and that can be conveniently handled by most exiting finite element solvers. To verify its capability and reliability, the element developed is used to solve two typical metal indentation problems. It has been shown that the present results agree very well with previously published data obtained using a different approach. (C) 1998 Elsevier Science Ltd. All rights reserved.
