The stress intensity factor (SIF) solutions of semi-elliptical cracks with high aspect ratios in plate and thick wall cylinder have been investigated under various assumed stress distributions. The authors have developed an automated analysis procedure to perform parametric studies on crack shapes and loading conditions. It consists of programs to perform automatic mesh generation, analysis execution including assignments of boundary conditions and SIF evaluations by virtual crack closure integral method. It was also found that SIF solutions for the thick wall cylinder and for the complex structure could be estimated by those for the flat plate.

Simulation for intergranular stress corrosion cracking based on a three-dimensional polycrystalline model

Kamaya, Masayuki*; Itakura, Mitsuhiro

Engineering Fracture Mechanics, 76(3), p.386 - 401, 2009/02

 Times Cited Count:38 Percentile:77.85(Mechanics)

In stress corrosion cracking of stainless steel, two different schemes of analysis of crack growth should be employed for the crack initiation phase and crack growth phase. However, this distinction is not clear-cut in the crack initiation phase, because initiation of crack tends to occur at the tip of a pre-existing crack and it can be regarded as crackgrowth. The contribution of this type of initiation dominant growth to crack growth was evaluated by a Monte Carlo simulation, and it was shown that the contribution of IDG to crack growth was large for small cracks.
