Design and application of safety production monitoring and measuring system for explosion products 火工品安全生产监测系统设计和应用
The quasi - static damage stage under the quasi - static stress field produced by gas from explosion . finally , the general model for blasting damage and fracture is gained . in the thesis , a gas - driven fracture propagation and damage localization at the crack tip model during explosion products are proposed 根据爆炸力学,将岩石的爆破损伤分为两个阶段来研究,第一阶段为爆炸应力波作用下的动态损伤阶段,第二阶段为爆生气体静态压力场作用下的损伤阶段,最终得出了岩石在爆破作用下的爆破损伤断裂全过程演化模型。
