In the previous chapters we learned how to model failure, yielding and hardening in triaxial compression. The failure and yielding will also take place for any straight effective stress path emanating from the initial preshear stress state \({{{p}'}_{0}}0\), provided inclination of this stress path is steeper than My (Figure 18.1a). If the slope of this stress path is smaller that My, the failure will never occur, but experiments show that the yielding will still take place, with the main plastic strain component being volumetric.
