On non-smooth dynamics

摘要: The fundamentals of non-smooth mechanics have been developed in Europe the second half last century and since then continuously extended improved. inclusion into classical multibody theory took place nineties allowing treatment large problems with unilateral contacts, which were not feasible before. One problem still consists relevant computing times, fifteen years could be brought down considerably, partly by a better theoretical description numerical algorithms. This paper describes evolution these processes leading today to quite powerful methods. Nevertheless progress this matter has yet come an end. Industrial examples illustrate theory.
