It was shown that characteristic properties, such as the yield stress, vary linearly with the logarithm of strain rate. Furthermore, it was observed that the onset of yielding under any state of stress is governed by the tensile yield stress or yield strain. The onset of yielding in a composite lamina was also characterized under multi-axial states of stress and varying strain rates. It was shown that yielding can be described by criteria entirely analogous to the Northwestern failure criteria. Yield stresses varied linearly with the logarithm of strain rate. Thus, a master yield envelope was obtained for the lamina for varying strain rates and states of stress. Excellent agreement was shown with experimental results.
