APPLICATION OF A JOINT MODEL TO CONCRETE-SANDSTONE INTERFACES. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

This paper describes a set of constitutive relations which describe the combined shear and dilational behaviour of bonded interfaces between concrete and hawkesbury sandstone. The model is based on the theory of shear hardening and softening elastoplasticity. The model incorporates the gradual degradation of the cohesive component of shear strength (i.e. softening) with shear displacement, as well as the mobilisation of the frictional component of strength (i.e. hardening) as the shearing creates a rupture surface. The model is capable of matching well the behaviour of bonded interfaces observed in laboratory direct shear tests. (Author/TRRL)
