本文用平板冲击产生平面冲击波的方法研究了环氧树脂的响应。特别地，冲击波速度-颗粒速度空间和冲击波速度-颗粒速度空间中的Hugoniot以及剪切强度随冲击应力的变化进行了研究。将本研究结果与前人的研究结果相比较，结果吻合得很好。已被用来确定剪切强度的横向应力的测量表明，在所研究的范围内，剪切强度随纵向应力而增加。此外，横向应力已被证明是减少后面的冲击前，这意味着在冲击载荷的这种材料的强度增加。这似乎可能是环氧基树脂的粘塑性性质的表现。
The response of an epoxy resin has been investigated using the methods of plate impact to generate planar shock waves. In particular, the Hugoniot, both in stress–particle velocity and shock velocity–particle velocity space, and the variation of shear strength with impact stress, have been investigated. Comparison of the results of this investigation with those of previous workers shows good agreement. Measurements of lateral stress, which have been used to determine the shear strength have indicated that shear strength increases with longitudinal stress in the range investigated. Further, lateral stresses have been shown to decrease behind the shock front, implying an increase of strength of this material during shock loading. It would seem possible that this is a manifestation of the viscoplastic nature of epoxy based resins.
