Some parametric analyses of contact elements

This paper presents some results of performed parametric analyses of the previously developed contact elements which are used to disretize the space between two mechanically interacting bodies or adjoining and/or disjoining non miscible media. The following characteristics and properties have been varied in the performed parametric analyses: the type and the rule of numerical integration, the influence of Poisson's ratio, the thickness of the contact zone, the influence of the size of non-linearity of the contact line and the number of elements in contact. The presented parametric analyses have been performed on simple and small sample problems, in which a large number of parameters can be varied economically.
