Contact problems play a dominate role in almost all engineering disciplines, thus
there is a huge demand for computational contact mechanics. One of the most impressive
application is crash analysis. In the scope of this master’s thesis contact
mechanics is approached in an object-oriented manner. A three-dimensional nonlinear
node-to-surface contact algorithm is derived and implementation details
are presented. For constraint enforcement the penalty method is used.
The thesis is composed of six chapters. The first two chapters give an introduction
to the topic and describe computational contact mechanics in the framework
of object orientation. Next, the basic theory is presented. The implemented
4-node contact element is formulated in the fourth chapter. After the contact
element is derived the object-oriented implementation is explained. Finally, examples
are presented and discussed.
