A LINEAR COMPLEMENTARITY METHOD FOR ELASTIC CONTACT PROBLEMS BASED ON THE PRINCIPLE OF VIRTUAL WORK

In this paper,a linear complementary contact condition is first derived,and then,base on the principle of virtual work and FEM,a linear complementarity method for elastic problems with friction is proposed.This method can avoide the tiresome iteration procedure used in previous work,and if there is no unloading,only one incremental step is needed for a solution. An exemple is given to demonstrate tlie correctness and effectiveness of the method.
