Stress Approximations by the H- and P-Versions of the Finite Element Method.

Abstract

The computational effort required for achieving a given level of precision in the root-mean-square measure of stress is examined. The main conclusion is that for most problems of practical importance it is not feasible to exercise substantive control of error in this norm by means of state of the art finite element technology. The computation and control of error of stress intensity factors is a much simpler problem. (Author)
