| Abstract: | Based on cavity expansion theory and modified fluid dynamics theory,the calculation method of depth of penetration on penetrating into semi-infinite metallic targets by spherical-nose steel projectiles is developed.According to the impacting velocity limit deduced by the limit of penetration,the calculation formula of depth of penetration limit is found,and compared with exprimental data.The practicability of this method is validated. |
