UNIFIED APPROACH FOR CONSTITUTIVE MODELLING FOR GEOLOGIC MATERIALS AND DISCONTINUITIES. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3
A unified hierarchical concept for modelling stress-strain behavior of solids and discontinuities is described together with verification with respect to laboratory tests from multiaxial testing of soils and rocks, and shear testing of joints and interfaces. The model allows progressive development of models starting with a basic model for isotropic plastic hardening with associative flow rule. The progression allows for adding of contributions of factors such as: nonassociative response; anisotropic hardening; damage and softening; pore water pressure; and the viscoplastic response. The models have been applied and verified for about 18 different soils, rocks and concrete, and joints and interfaces including soapstone, Ottawa sand, rock salt, Leighton buzzard sand and Munich sand.
