General description of the condition

This conditions represents the main part of the algorithm to solve contact problems. The algorithm is based on a surface to surface penalty formulation using a master and a slave contact surface. It is formulated to solve frictional contact problems in structural mechanics, the algorithm is formulated in a finite deformation context.

This condition and the underlying algorithm for contact problems has not been tested by means of a broader range of benchmark examples so far. It seem tio work quite fine for a number of different examples, but I do not give a guarantee that it is free of errors in its formulation or its implementation.

Formulation of the two body contact problem
