Abstract:
An innovative safety assessment method of local wall thinning of straight pipe under the combined action of internal pressure, axial force, torque and bending moment was proposed. A simple formula for calculating hoop stress，axial stress, and shear stress was derived considering the combined action of internal pressure, axial force, and torque. Aiming at the straight pipe with local wall thinning defect, the limit bending moment calculation method was established on the basis of plastic failure theory, and the strength criterion was also proposed using Mises equivalent stress under the above-mentioned combined action of multiple loads. Finally, the dual criterion assessment method based on both the strength condition and the limit bending moment load was established and is applicable to evaluate the safety of the pipe with local wall thinning defect under the combined action of internal pressure, axial force, and torque.
