对泡沫塑料落锤冲击试验的解析

Analysis of Drop-hammer Shocking Test About the Foamed Plastics

结合KBM法和能量法求解泡沫塑料试件受冲击的压力、变形、加载速度及应力应变关系 ,得到了相当准确的结果。同时 ,系统地阐述了粘性对泡沫塑料冲击试验的影响 。

In this paper,the KBM method and energy method are combined to calculate the pressure,deformation,loading speed and stress strain relation of the foamed plastic specimen,the results show that the calculation is quite accurate in drop hammer shocking test.In the meantime,the paper relates the influence of viscosity property on the foamed plastic shocking problem which can be used as a theoretical basis for engineering application.
