A thin-walled cylinder made of a brittle material is subjected to an internal pressure p.. It has a diameter of 2.55m and a wall thickness of 10.0mm. The Mode I fracture toughness for this material is Ke = 7.5MPam. Structural examination discovered a through-the-thickness longitudinal crack of 2.75cm in the length of the cylinder. Assuming that the stress intensity factor can be approximated as K = na and the vessel wall can be analyzed as a thin flat plate in tension, estimate the maximum internal pressure that the cracked cylinder can hold.
