A comparative study between two smoothing strategies for the simulation of contact with large sliding

Autor: Nicolas Chevaugeon, Benoit Magnain, Alain Batailly

Publikováno v: Computational Mechanics. 51:581-601

The numerical simulation of contact problems is still a delicate matter especially when large transformations are involved. In that case, relative large slidings can occur between contact surfaces and the discretization error induced by usual finite
