Abstract Material heterogeneity plays an important role in the blasting induced rock fracture. However, the
investigation of the effects of material heterogeneity is limited by the numerical methods for dynamic
fracture. In the work, we propose a peridynamic model for brittle rock with heterogeneous micro-modulus
and critical stretch to investigate the effects of material heterogeneity on the blast-induced rock crack
initiation and propagation. The discretization in polar coordinates is introduced into the proposed model to
avoid the fallacious directional guidance to the crack initiation around the hole. The proposed model
satisfies the More >
