SPH 기법을 이용한 복합 적층판의 초고속 충돌 해석
Numerical simulation of hypervelocity impacts on laminated composite plate targets using SPH method
- 발행 : 2004.11.03
초록
This paper is concerned with numerical simulation of hypervelocity impacts(HVIs) of a projectile on laminated composite plate targets using SPH method. A one-parameter visco-plasticity model and damage model is used to describe the HVIs response of composite materials. The numerical simulation was carried out for a steel projectile striking to aluminum plate targets and for an aluminum projectile striking to laminated graphite/epoxy (Gr/Ep) composite plate targets. Through the numerical simulation, comparison with the HVIs response of isotropic materials and composite materials is discussed.
