The Dynamic Mechanical Response Properties of Dyneema UD66 Laminates

The one dimensional plane strain dynamic loading technique and Lagrange analysis method are used to study the dynamic mechanical response properties of Dyneema UD66 laminates under strong stress pulse loading. The distributing orderliness of the state parameters along time and space in the flow field are obtained. The dynamic mechanical response characteristics are analyzed according to dynamic mechanical theory. A constitutive equation is obtained on the basis of the results of experiment and Lagrange analysis. The results show that the material has a good property to absorb energy of shock wave and a obvious property of relative to strain rate.
