Paper presented at the 2nd North American Rock Mechanics Symposium, June 19–21, 1996
Paper Number: ARMA-96-1145
... 1. INTRODUCTION ABSTRACT: Understanding the fracture mechanism of brittle rock for shear rupture is essential to the study of the mechanisms responsible for rock fracturing. To analyze these types of failure mechanisms, the stress intensity factor of the fracture has to be defined. Research...

Paper presented at the 2nd North American Rock Mechanics Symposium, June 19–21, 1996
Paper Number: ARMA-96-1707
... ABSTRACT: This paper describes a model that predicts the moduli for brittle rock loaded by compressive principal stresses. All inelastic deformation is assumed due to microcracks that open under local tensile stresses caused by small scale heterogeneities. For axisymmetric loading...

Paper presented at the 2nd North American Rock Mechanics Symposium, June 19–21, 1996
Paper Number: ARMA-96-1721
... ABSTRACT: In this paper, laboratory studies and numerical modelling of induced anisotropic damage in a brittle rock are presented. Triaxial compression tests on core samples are first used to determine basic features of deformation and failure of the material. True triaxial block tests...
