Abstract:

Conventional finite-element models are based on displacement or velocity fields which are at least continuous. However, it is known that perfectly plastic materials may involve discontinuities of the tangential velocity component along certain lines. In this investigation, two two-dimensional finite element models are proposed which will allow for such discontinuities.
