Abstract:The finite element software JIFEX is developed with the application oriented concept for complex structures of general purpose engineering. The software integration of the finite element analysis, structural design optimization, pre- and post-processing developed with advanced platform Windows 95/NT is implemented. Among its versatile facilities of analysis and optimization, the 3-D contact analysis is one of the most important features. In this paper, a combined Parametric Quadratic Programming (PQP) and iteration method is presented to avoid the difficulties of unknown slip direction of the tangential displacement at contact point and exhausting computing time. The numerical algorithm of 3-D contact analysis and application examples are presented with brief introduction of the application-oriented software JIFEX. Copyright (C) 1999 John Wiley & Sons, Ltd.
