ADAPTIVE FINITE-ELEMENT ANALYSIS OF LARGE-STRAIN ELASTIC RESPONSE

Some basic studies and developments for adaptive procedures in large s train finite element analysis are presented: an evaluation of higher-o rder elements, two pointwise indicators for errors in stresses, a mesh generator for remeshing on the deformed configuration of the body, an d a general mapping scheme for transferring solution variables across models. The methods discussed constitute the ingredients of a proposed adaptive process that is demonstrated in solutions of two-dimensional stress analyses of rubber-like materials including contact conditions .
