密实介质中冲击波衰减特性的近似计算

AN APPROXIMATE THEORETICAL MODEL FOR THE ATTENUATION OF SHOCK PRESSURE IN SOLID MATERIALS

对密实介质中冲击波峰值压力的衰减建立了一个近似的计算模型，并利用该模型分别对铝、钢和有机玻璃等介质中的冲击波衰减特性进行了计算。算例表明与实验结果吻合较好，从而在一定程度上验证了模型的有效性。

An approximate theoretical model for the calculation of attenuation of shock pressure in solid materials is presented.Based on this model,the attenuation characteristics of shock pressure in aluminium,steel and PAMM are obtained.The cal-culated results show that they fit well with experimental data.
