Finite element method and its usable applications in wear models design

FEM models allow to perform more accurate calculations of contact strength and to predict the wear characters of materials. The prognosis of material behavior under load makes it possible to save resources and to abandon a trial-and-error method. The development of a FEM model as well as operating with FEM programs is a complicated and time-consuming process. The skills of model simplification become more and more important. The shape and the number of elements, moduli of elasticity of materials and contact stiffness parameters should be also considered. At this moment there is no usable application for FEM models creation available for wear calculations. In this paper usable application for contact stress FEM calculations of coated bodies is offered, that can be used by engineers of different areas.
