Abstract
Rocks in nature are often subjected to cyclic loads caused by earthquakes, which still exist after the rock reaches its maximum bearing capacity. To obtain the crack propagation characteristics of rocks under post-peak cyclic loading, notched granite beams were tested by means of three-point bending test method combined with digital image correlation (DIC) and acoustic emission (AE) technology. The horizontal strain, horizontal displacement and...
