S TRESS - STRAIN CYCLIC CURVES

T

he stress-strain cyclic curves of the material have been obtained by performing a step-up test for both proportional and non-proportional strain paths. The proportional strain is represented by a push-pull (PP) test, while the non-proportional loading is represented by a circle loading path (CI) (Fig. 5).
