▎ 摘　　要

NOVELTY - The method involves establishing a geometric model of a quarter-shot in a SOLIWORKS and deriving an IGS file. A bullet-IGS file is introduced into a LS-DYNA software. A ceramic layer of a target plate is modeled by a SPH method. The lagrange modeling process is performed to a carbon nano-layer, a graphene layer and a high-strength glass fiber layer. The ceramic layer and the carbon nanometre layer are bonded by a ceramic layer. An elastic core material uses a Johnson-cook constitutive model and a failure model to describe a material response of the elastic core materials under the action of dynamic load. A Chang-Chang failure rule is used to describe different failure forms generated when fiber is stretched and compressed. USE - Ceramic composite armor anti-penetration numerical simulation method for anti-armor weapon destruction capability. ADVANTAGE - The method effectively simulates the elastic core and ceramic crushing phenomenon, and the composite back plate layer of debonding phenomenon, reduces SPH particle and finite element grid coupling the calculation amount, and improves the calculation precision and calculation efficiency of the simulation model. The method solves the problem that the existing ceramic composite armor anti-intrusion numerical simulation is difficult to simulate elastic core cracking, calculating precision and calculating efficiency is not high. The problem of brittle material impact fracture and conventional finite element model (FEM) grid method only by deleting the grid to simulate the problem of the breaking process is fully considered. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the ceramic composite armor anti-penetration numerical simulation method. (Drawing includes non-English language text)
