摘要：

The paper gives an algorithm for the analysis of systems with unilateral constraints through the finite element method in the form of a classical mixed method. Given that both displacements and forces are variables in the system of governing equations, the procedure for the incremental parametric loading as a part of the analysis of structurally nonlinear systems allows varying the respective parameter, tending from << hard >> loading based on the load parameter towards << soft >> loading based on the displacement (configuration) parameter. The efficiency of the algorithm is shown by the example of a beam with unilateral constraints. (C) 2016 The Authors. Published by Elsevier Ltd.
