【Abstract】 A great number of fractures of different types of rock are examined by electrical scanning and optical microscope to investigate micro-mechanism of rock fracture. Initiation and propagation of cracks in brittle rock are analyzed by using model of Cottrell’s dislocation pile-ups based on which macro-phenomena are explained.更多还原
