Bending-damaged fracture criterion and numerical implementation of limestone beam under three-point bending test

Frontiers in Earth Science, 2023
To study the characteristics of tensile cracking by rock-bending damage, the bending stress–strain curves and the cumulative ringing counts were obtained by a three-point bending test and acoustic emission (AE) monitoring of limestone beams. Based on the

Crackling noise in three-point bending of heterogeneous materials [PDF]

Physical Review E, 2011
We study the crackling noise emerging during single crack propagation in a specimen under three-point bending conditions. Computer simulations are carried out in the framework of a discrete element model where the specimen is discretized in terms of convex polygons and cohesive elements are represented by beams.
