Abstract

The nonlinear complementarity problem formulation developed by the author for a general three dimensional frictional contact is reviewed, and succeeding works on extensions to various areas of mechanics are summarized and discussed. 1. Introduction Difficulties involved in a contact analysis come from several different sources even without considering material nonlinearity of contacting bodies. The first one is that the extent of contact region is not known a priori, and the second is that the contact friction law is discontinuous, and again the local status of contacting points is not known. For three dimensional problems, the direction of friction force has also to b
