ess, the effect of normal stress, the effect of intermediate principal stress, the effect of intermediate principal shear-stress, symmetry and the convexity of yield surfaces. The research on the SD effect, the effect of hydrostatic stress and the effect of normal stress have developed rapidly becau

Luc Trouche,Ghislaine Gueudet,Birgit Pepinfied strength theory are described. The mathematical expression of the unified strength theory is simple and linear, however, the yield surface of the unified strength theory is piece-wise linear. The plastic flow vector exists singular points for the piecewise-linear yield functions. The flow vecto

It gathers together a lot of basic properties (some of which are usually referred to in research papers as belonging to folklore) and very recent and sometimes deep results. I have chosen a fairly strict geometrical approach, which requires some knowledge of basic project
