| Abstract: | A method for calculating the damage caused by the straim wave is presented in this paper.By combining the dynamic effect of strain wave with quasistatic effect of explosion products,the author analyses the whole process of fracture and correts the defect of prevailing theories. The paper also reveals the mechanism of the preliminary loading effect of stress wave proposed by kutter. |
