摘要: Technology allows the production of advanced (heterogeneous) materials controlling properties on an increasingly local scale, e.g. layered, graded, granular and fiber-reinforced. In this paper efficiency Multigrid method for 3D stress calculation involving such is investigated. Results are validated using model problems full potential demonstrated two representative problems. The developed algorithm facilitates solution with high accuracy dense grids standard computers. It has excellent prospects use in performance prediction, analysis numerical (local) design optimization tribology contact mechanics
