Fast algorithm for simulation of normal and oblique penetration into limestone targets
Description:Fast algorithm for simulation of normal and oblique penetration into limestone targets[J]. Applied Mathematics and Mechanics English Edition , , 38 5: A fast algorithm is proposed to predict penetration trajectory in simulation of normal and oblique penetration of a rigid steel projectile into a limestone target. The algorithm is designed based on the idea of isolation between the projectile and the target. Corresponding factors of influence are considered, including analytical load model, cratering effect, free surface effect, and separation-reattachment phenomenon.
