对粘弹性材料力学性质的再认识

Reappraisal of the Mechanics Quality of Sticky-Flexibility Materials

以文献 [1 ]的线性理论为基础 ,分析粘弹性材料动态压缩试验的压力、变形及加载卸载速度 ,据此绘制材料的应力应变曲线 ,证明粘弹性材料动态压缩试验的加载与卸载曲线不重合 ,指出卸载阶段结束时试件有不能立即恢复的粘弹性变形 ,并导出了与粘弹性回复曲线对应的指数衰减函数。

This artcile is based on the linear theory of Article I,analyzes the pressure、deformation loading and unloading velocity of dynamic condensing ltst of sticky flexibility materials,prove that the loading and unloading curve of dynamic condensign test of sticky flexibility materials are out of coincide,point out that the test samples have sticky flexibility that can't restore instantly,and conclude the exponential attenuation function corresponding to sticky flexibility restoring curve.
