Rock is a material subject to initial damage. Rock blasting-induced damage model is the most commonly used constitutive model for numerical simulation of rock blasting. At present, however, most models neglect the effects of initial damage on blasting. To this end, this paper explored the merits and demerits of typical blasting- induced damage models. Then, a rock blasting-induced damage model was proposed by modifying the typical blasting-induced damage models, with the effects of initialdoi:10.3303/cet1866074 doaj:cf79da90ca504991ac4d62503a53d93c fatcat:bqwpd3gbfbfxfn4heg47p7sdni
