Numerical modeling and analysis of the ballistic impact response of ceramic/composite targets and the influence of cohesive material parameters

Hybrid ceramic/composite targets are acknowledged to provide effective impact protection against armor piercing projectiles, which is why the research on this topic continuously developing further. In work, a nonlinear dynamic finite element (FE) simulation method developed systematically explore ballistic perforation behaviors of hybrid ceramic/woven-fabric reinforced polymer (WFRP) composite when impacted by non-deformable projectile. The system composed an alumina ceramic plate forming front surface and glass or carbon WFRP back-up plate. simulations carried out using ABAQUS/Explicit FE code, wherein three different constitutive material models formulated implemented. Johnson–Holmquist damage used for behaviors, respectively. brittle fracture fragmentation failure criteria based fibers matrices materials during considered. Besides, interlaminar delamination between plies as well interfacial decohesion modeled cohesive method, interlayer degradation described traction-separation law. accuracy model validated with available experimental analytical results. What’s more, process projectile mechanism each layer in backplate profoundly explored. Meanwhile, numerical evaluate changes energy panels. influence key parameters, such interface properties friction, performance terms absorption capability additionally addressed. For preliminary early design phase, present could efficient approach predictions responses ceramic/FRP composites.
