摘要：

Under some hypothesis, the Drucker-Prager(D-P) criterions can be used approximately instead of Mohr-Coulomb(M-C) criterion. The foundation of transformation methods from M-C to D-P from energy view is firstly set forth; and then emphasis is given to investigate the square error of distortion energy density, which are needed for reaching M-C yield and D-P yield respectively, provided the same Lode angle in. plane. Based on the least square method, the relations of parameters for M-C and D-P are obtained providing minimum of the square error of distortion energy density. The result obtained in the approach is according to the equivalent area's approach, the interpretation in energy view for the transformation method in equivalent area's approach is presented.
