... Abstract Cracks triggered by Carbon Dioxide initiated Stress Corrosion Cracking (SCC-CO 2 ) have been identified as a new failure mode in flexible pipes, yet a method of predicting its occurrence, especially the stage of crack initiation (T 1 ) is lacked in the industry. The root cause of SCC...

... formulation [3], where the fatigue model considers the bond’s cyclic in-plane, shear, bending, and torsional deformation. We successfully identify the critical locations for crack initiation in the jacket under constant amplitude cyclic point loading. We further evaluate the number of load cycles required...

... and asymmetric load. Therefore, the effect of mean stress on the crack initiation life of the stiffened plate, the basic unit of ship structure, is investigated in this paper. The crack initiation experiments of welded stiffened plates under different stress amplitudes and stress ratios were carried out...

... scatter diagram. 5% strain drop criteria is introduced to define crack initiation life. Experimental results including the test results from previous study are evaluated and compared with DNV-CN 30.7 (2005) and Matsuoka's method for the estimation of crack initiation and propagation life. From the result...
