MECHANISM ANALYSIS ON PELE IMPACTING THIN TARGET PERPENDICULARLY
Obvious lateral effect can be seen in PELE impacting target, and there are several basic parameters which affect the lateral efficiency. On the basis of experimental results, analysis on the stresses of PELE during its penetration into the target is made and the mechanism of the production of lateral effect is illuminated. On some hypotheses, models on the residual velocity and the radial velocity of PELe penetration into a thin target are established, and the theoretical results are found to agree with the experimental results approximately. Studying abovementioned outcome, one can easily find that the ratio of compressive to tensile stress of jacket, the Modulus of elasticity and Poissons ratio of the filling material and the impact speed of the penetrator affect the lateral effect markedly. This study can be of some assistance in the design and betterment of PELE projectile.
