Weba plastic strain increment dσ/H, while the total strain increment is dσ/T. Hence the relationship between H and T is 1 T = 1 E + 1 H (1) In an annealed material, H is considerably greater than T at the initial yielding, but these two moduli rapidly approach one another as the strain is increased. The differ- WebThe size of the plastic strain increment is therefore related to the total increment in strain, the current stress state, and the specific forms of the yield and potential surfaces. The …
