Abstract
In a given set of impact velocity conditions, the numerical simulation is performed to analyze the effect of the projectile diameter on perforation of the front wall of gas-filled pressure vessels. Then the critical stress value is estimated based on the stress intensity factor which is determined by simplified linear elastic fracture mechanics, and the computational model is built. The model is presented by postulating the existence of two-radial cracks that emanate at the boundary of a circular hole. The result shows that a good correlation between experimental and computational results is obtained. If the ratio of single crack length to hole radius exceeds the value of 0.5, the hole with radial cracks can be considered as a straight crack. The projectile with small kinetic energy is likely to lead catastrophic burst of pressure vessels.
