摘要: Abstract The mechanism of fracture coalescence is reported from uniaxial compression gypsum samples with two open or closed cracks. Coalescence can be caused by tensile failure, shear failure mixed and failure. In this paper, the observed in tests modeled numerically using a modified G -criterion displacement discontinuity method (DDM). predicted path critical load are good agreement experimental results. It also unveiled study that mode II key reason for between non-overlapping
