A CONSTITUTIVE MODEL OF SOILS FOR EVALUATING PRINCIPLE STRESS ROTATION. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

A constitutive model for soils is proposed in which the general strain increments are directly related to the general stress increments. The stress-strain matrix between the strain increments and the stress increments is expressed in general coordinates. In order to evaluate the influence of rotation of the principal stress axes on strains, "principal stress rotation tests", (in which the stress path is the circumference of a Mohr's circle), have been carried out by a "two-dimensional general stress apparatus" using a stack of aluminium rods. Simple shear tests and liquefaction tests due to principal stress rotation are also analyzed by the proposed model. The model is extended to a three-dimensional one. (TRRL)
