Abstract: Explosive test and numerical simulation were carried out to examine the damage effects of high explo?sive projectile to thick tube. According to Tresca guide line and truck cylinder’s strength theories, the criteria of tube’s failure were deduced. The effects of fragment’s figure, aviation direction mass, velocity on damage were explored. The research results indicate that if high explosive projectile explodes near or in front of the thick steel tube in some short distance, the generated fragments’ impactions will cause clear damages to the steel tube. The given data and the analyses to damage law can be used as reference basis to analyses of thick tube ’ s viability and to design and improvement of warhead.
