The failure process of brittle material is closely related to the propagation of crack.The microscopic structure characteristics directly determine the macroscopic mechanical behavior.But currently limited by the test instrument,the brittle failure mechanism can't be fully understood,and the test method must be combined with numerical method.Firstly,the uniaxial and triaxial compression tests were finished by mechnical testing system(MTS),and the acoustic emission(AE) signal was monitored… CONTINUE READING
