Abstract The numerical investigation of experimental work on microcracking and fracture growth around openings in blocks of rock, making use of a newly developed anisotropic damage model, is described. The constitutive equations extend the concepts of continuum damage mechanics in such a way that general compression/extension stress states can be accommodated. Backpredictions of a few standard triaxial tests on quartzite demonstrate the suitability, capability and accuracy of the model… CONTINUE READING
