Based on viscoelastic peridynamic method, a numerical model of a three-point bending
concrete beam with an initial crack is established in this work, whose accuracy and
rationality are verified by comparing the fracture modes calculated by this model with the
experimental results. The paper analyzed the angle of crack propagation and the evolution
of energy, displacement, strain, and strain rate in the beam by the verified numerical model,
while a total of 24 numerical examples with different initial crack positions and loading …
