Abstract

The discretization of an elasticity problem using element techniques seldom produces an exact representation of the original geometry. In the general case. an originally smooth curved boundary is approximated in the numerical model by a series of curved or flat pieces. the elements, whose joints are not smooth, corners being induced as a consequence. In this work, the effects of the above mentioned corners in two dimensional receding contact problems are investigated when the Boundary Element Method (BEM) is used. The relevant effects induced by corners are identified. and a coherent explanation is proposed for the obtained results of several examples. The most relevant consequence of the study is that some types of boundary elements are to be discarded when the contact problem involves some identified peculiarities.
