This free energy function is capable of describing the pressure-dependent elastic behavior of soils. The new constructed dissipation rate function accounts for the frictional mechanism of energy dissipation. Based on this dissipation rate function, the non-associated flow rule can be obtained. Furthermore, the convexity of the yield surface that is derived from the dissipation rate function is proved. Predictions of the behavior of a soil sample using this new constitutive model agree well with triaxial test data under drained and undrained conditions.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000429500500010</style></accession-num><notes><style face="normal" font="default" size="100%">Gc0xfTimes Cited:10Cited References Count:39</style></notes><section><style face="normal" font="default" size="100%">102</style></section><auth-address><style face="normal" font="default" size="100%">Peking Univ, Dept Mech &amp;amp; Engn Sci, Coll Engn, Beijing 100871, Peoples R ChinaShanghai Elect Windpower Grp, Shanghai 200241, Peoples R China</style></auth-address></record></records></xml>
