陶瓷/金属复合装甲冲击响应的三维SPH法分析
Three-dimensional SPH analysis of impact responses of ceramic/metal composite armors
摘要
Abstract
A three-dimensional smoothed particle hydrodynamics (SPH) code was developed to simulate the penetration of ceramic/metal composite armors by projectiles. The Johnson-Cook and John-son-Holmquist Ⅱ constitutive models and the Mie-Griineisen equation of state were incorporated into the developed code to describe the nonlinear deformation and damage features of metal and ceramic materials. The typical displacement-time curves computed by the developed SPH code are in good a-greement with the experimental results. The numerical simulations can represent the major features of the composite armor system such as, projectile erosion, ceramic conoid formation and splash, backing plate failure and so on. And the obliquity effects on the penetration-resistance ability of the composite armor were investigated. The results indicate that there exists an optimal obliquity for the penetration-resistance ability.关键词
