Linear transformed stress space and its application

A linear transformed stress space method is proposed. The generalized nonlinear strength theory (GNST) is transformed into Mohr-Coulomb criterion in the new proposed stress space. Thus, the GNST can be regarded as Mohr-Coulomb criterion in new stress space. The strengths and stress-strain experimental results of two kinds of clay are collected and analyzed in the new linear transformed stress space. The consistency between the experimental results and the theoretical predictions shows that the transformed stress space method is effective.
