| Abstract: | Summary A two-surface theory based upon experimental results is presented. The theory utilizes the concept of a yield surface and a loading surface to describe the essential features of the time-independent inelastic behavior of materials. The theory is implemented in a computer program and its predictions are compared to a variety of axial-torsional experimental data including both proportional and nonproportional loading.With 11 Figures |
