COMBINED ALGORITHM OF DOMAIN DECOMPOSITION AND h -ADAPTATION FOR THE SOLUTION OF CONTACT PROBLEMS OF ELASTICITY

摘要

We propose a combined algorithm for the solution of the problems of contact of elastic bodies. This algorithm combines the iterative method of domain decomposition and the h -adaptive scheme based on the comparison of the results of the finite-element and boundary-element methods. The numerical analysis of a test problem shows that the mesh refinement performed by using the proposed algorithm reveals singularities of the stress field near the contact area and the total number of unknowns significantly decreases, as compared with the case of uniform partition.
