摘要
本文应用叠加方法,研究了在球形装药矩形脉冲荷载作用下的应力波性质,导出了波动方程解的数学表达式;并分析了径向和切向裂隙产生的机理.
By applying superposition principle the paper discusses the characteristics of stress wave under rectangular impulsive load with spherical charge. The mathematical expression of the solution of the wave equation has been derived, and the mechanism of producing radial and tangential cracks under blast load has been analyzed.
