Abstract
Limestone is a widely used building material, and its deformation and failure process is affected by unloading or other disturbing loads. To explore the progressive propagation law of micro-cracks, energy conversion in the progressive failure and nonlinear breakage mechanism in limestone, 3D acoustic emission experiments are conducted on preloading under cyclic loading and unloading with low frequency and unequal amplitude. The results revealed...
