"Rupture and Instability in Granular Materials" shared by Prof. Hicher

Within the confines of material instability, two major criteria can be noted. The first criterion refers to the vanishing of the determinant of the constitutive tensor which signals homogeneous failure at the plastic limit condition, whereas the second criterion involves the vanishing of the determinant of the acoustic tensor (Rice's localization criterion) which coincides with the emergence of plastic strain localization. For materials with an associative flow rule, the symmetry of the elasto- plastic tensor implies that the two aforementioned criteria happen to comcide. However, geomaterials are known to be non-associated in character, which means that the symmetry in the elasto-plastic tensor will be lost.
