A B S T R A C T The stress intensity factor is the linear elastic fracture mechanics parameter that relates remote load, crack size and structural geometry. It predicts very accurately the stress state. In this work SIF (Stress Intensity Factor) for a single cracked pressurized cylinder is calculated. Ansys10 Finite Element Analysis software was used in this study. This software was used to obtain the nodal forces at the crack tip as well as the displacements in the vicinity of the crack tip.
