摘要：
Acoustic emission monitoring techniques are a powerful tool for analyzing deformation behavior and fracture characteristics of rock samples. Uniaxial compression tests have been carried out on three different types of sandstone for a better understanding of acoustic emission response with respect to rock deformation and damage development. All sandstone samples reveal congruent characteristic acoustic emission patterns which correlated directly with distinct stress-strain stages. However, the acoustic response and development within the individual stages prove to be entirely different due to variations in their microstructure.
