In this paper, the dynamic compressing experiments for the matrix material of the tungsten alloys which have been three different deforming(0%、 32.6%、 44.6%) processed have been performed by the experimental technology of separated Hopkinson pressure bar and many accurate datum have been obtained. Also the three materials have been compared with each other and analyzed. The results show that the optimized values are in a certain range to optimize the materials by changing their deforming technology. The parameters of constitutive model of Johnson-Cook have been fitted based on the datum. Then proceed to the next step, adiabatic shear band of these three matrix materials has been analyzed with finite element method. The result shows that the relations between stress and strain are different because of the differences of technical process of the three materials, but they are in great commonness in the material experiment and in great coherence in the distribution of time and space, which can been seen from the space distributing figures of plastic strain.

The relationships between strain and stress of several kinds of high strength fibers, such as Kevlar, Twaron and Dyneema were obtained, and the dependence of mechanical properties of fibers on the strain rate was gotten and explained from the microstructures and deformation mechanism of fibers. Then, the damage and failures of plates with the reinforcement of fibers under high velocity impacting were studied experimentally. Based on experimental results, a set of equations was presented to depicted the deceleration of penetrator. The dynamic response of fiber cluster and sandwich were simulated successfully with a new algorithm and code, which was developped by our group. The coupling effect of stress wave and thermal conduction could be considered with acceptable accuracy and CPU time.
