摘　　要：该文就子母弹的开仓问题 ,通过建立合理的由不同材料组成的不等截面杆模型 ,利用一维线性应力波理论 ,研究了在炸药爆轰这一极短暂的过程中 ,应力波在各介质间的传播 ,并通过大量的算例 ,着重探讨了载荷作用时间以及子弹排列等对应力波传播的影响规律。该文的工作对类似子母弹的研究。A one dimension linear theory of stress wave was applied to the shrapnel's rupture.The propagation of stress wave in materials during the transient time when the dynamite blasts is investigated by establishing a sound bar model made of several materials with varying sections. Based on a lot of calculation, the rules about how the load, the acting time and the collocation of bullets will influence the propagation of stress wave are especially discussed. The work here does an important referential contribution to the design of similar shrapnel.
