STRESS INTENSITY FACTOR FOR CENTER CRACKS IN CYLINDRICAL PIPES UNDER BENDING MOMENT, AXIAL STRESS AND INTERNAL PRESSURE

Abstract

In this study; the stress intensity factor was computed for a cylindrical object that was under effect of bending moment, axial stress and internal pressure. In order to make the calculations easy, the stress intensity factor was calculated individually for bending moment, axial stress and internal pressure. Then, the result were superimposed to have a final stress intensity factor for the concerned object. The calculated stress intensity factor is known as Mode I, which corresponds to "opening mode". Furthermore, it was assumed that there were some initial radial cracks around the center line for a given object and the amount of change on the stress intensity factor was discussed.
