Abstract


The composite rod in the elongated elastic core coated with low density, high Young's modulus of the composite structure of the jacketing material rod body . To explore this the profiled rod penetration ability , this article on the phenomenon the the composite structures rod penetration of vertical semi- infinite target launched . Penetration ability of different structural composite rod ( mainly the different structure of the sheath ) , the article application of ANSYS / DYNA software simulation analysis, the law of the jacket structure terminal effect . As well as the analysis of composite structures rod crater and expand Bjerke research , put forward the concept of \On this basis , based on the physical image of the vertical penetration , combined with classic armor-piercing theory to establish a theoretical model the the composite structures rod penetration of vertical semi- infinite target , analysis of various parameters on the penetration of vertical . Finally, the semi-infinite target of composite structures rod penetration test , test results and model calculations approximate consistent .
