Abstract Poly-p-phenylene benzobisoxazole (PBO) fiber is a new with high ballistic performance, such as excellent heat and flame resistance super mechanical properties. Consequently, increasing attention has been paid to its applications in the field of resistance. To identify damage mechanism PBO composite target caused by high-velocity penetration cylindrical projectiles energy conversion mod...

Abstract In order to predict the ballistic limit of ceramic/ UHMWPE composite protection, a theoretical model ceramic/UHMWPE protection for projectile was established based on A-T and fiber energy dissipation model. impact process, fragments will experience ceramic dwell, fragmentation layer dissipation. The obtained is compared with experimental simulation results. results show that residual v...

Abstract A multilayer constrained alumina ceramic metal composite armor is designed in this paper. The effect of interlayer steel thickness on penetration process tungsten alloy piercing projectile studied by the test and finite element simulation. results show that case same layer ceramics equal surface density, thicker plate away from impact is, better support to sandwich is. It beneficial ma...

The penetration of projectiles into targets has a broad background in engineering. In this work, numerical simulations the projectile-target problem are conducted using Finite Element Method (FEM), Smoothed Particle Hydrodynamics (SPH) and Element–Smoothed Adaptive Coupling (FE-SPH ACM) based on LS-DYNA software package. First, experiments aluminum ceramic simulated. experimental simulation res...

Abstract In order to study the penetration ability of fragment simulation projectile(FSP) armored steel target, and detect protection target plates with different thicknesses. Combined numerical experiment, process FSP on thickness ratios is studied. The design implementation preparations were made for damage plate by fragments, relevant data obtained analyzed. analysis results show that finite...
