摘要：

This paper deals with the bending of a beam on an elastoplastic foundation as a contact problem with unilateral constraints between the beam and the foundation. The incremental problem is formulated as a variational one, and a Reissner type functional is built up. The contact problem is solved by an iteractive method, using the finite element method in a mixed approach in the computational model. Numerical examples are presented which demonstrate the efficiency of the method.
