Concrete failure simulation method based on discrete element method
Engineering Failure Analysis（2022）
Abstract
•A high-efficiency calibrating method of meso-parameters in PFC have been improved.•The complete process of crack initiation, propagation and coalescence have been simulated DEM.•Four-point bending strength test and direct shear strength test has been carried out by DEM.
