Simplified Evaluation of the Maximum Stress Intensity Factor Range of an Inner-Surface Circumferential Crack in a Long Cylinder under Steady State Thermal Striping

Abstract

Simplified method to evaluate the maximum stress intensity factor (SIF) range of an inner-surface circumferential crack in a long cylinder under steady-state thermal striping was presented within this paper. By the method, the desired maximum SIF range can be evaluated with an engineering accuracy once the mean radius to wall thickness raio r_m/W of the cylinder is specified. No transient SIF analysis nor sensitivity analysis for striping frequency is necessary.
