Abstract: In this paper, the numerical study is carried out for three test problems of projectile penetration; a tungsten projectile impacting on a steel target at 1000 m/s, a steel projectile impacting on a steel target at 1000m/s. and a steel projectile impacting on a. aluminium target at 1000 m/s. The basic equations of compressible fluid and elactic-plastic flow in two dimensions and Eulerian typical CPG-LTDL code are used in the numerical calculation. The results of computation are in good agreement with the exp...
