Modelling of contact problems with friction. Implementation by the code ZeBuLoN using C++ This paper presents a general tool to solve contact problems with friction with special emphasis on forging processes. This tool allows to take into account a very large class of contacts between rigid or deformable solids. The associated software is written in C++. The efficiency of the approach is illustrated by three examples: the numerical investigation of windscreen wipers, of thrust block, and of a three-dimensional contact problem.
