I'm not sure what you mean by strength degradation so let me provide some relevant information. One way of looking at it is to see the accumulated plastic strain. You'll need to use user-defined result to plot NLEPEQ to plot this quantity. This tells you how much plastic strain is accumulated over the cycles of loading.nAlso, note that in cyclic loading the material experiences Bauschinger effect which is not captured by isotropic hardening. This is something you may want to consider in assessing strength degradation.n
