SURFACE CONTACT WITH FRICTION BETWEEN POLYHEDRIC DISCRETE ELEMENTS
Marc VINCHES, Claude BOHATIER, Ali RAFIEE
In this communication we propose the modeling of the contacts between rigid solids on a principle of their localization at nodes. The results of the application of Non-Smooth Contact Dynamics (NSCD) method to investigate the stability conditions of jointed rock slopes, and of several masonry structures in real scale, are presented in this paper.
The theoretical basis of a new approach which makes it possible to simultaneously consider at the same time a better localized stress analysis and a reduction of computation time, is discussed
