Abstract : Due to the extreme complexity of the problem, it has been necessary to formulate theories of plasticity which grossly simplify the material behavior. While, in many cases, these theories give satisfactory results, there are other cases in which they fail. Therefore an investigation has been initiated with the purpose of evaluating presently used theories and assessing the possibilities for improvement for the cases in which the classical theories are not satisfactory. The present paper describes a system for testing, which includes a data-acquisition system and a computer program for comparisons between test and theory. A few test results are included which verify the adequacy of the system and illustrate some facets of the problem. (Author)
