Investigation of fatigue crack growth (FCG) phenomenon has been a topic of interest for the last few decades. Among related studies, computational methods have been commonly used due to their availability and ease of use to obtain the corresponding output. There have been several tools developed for this purpose. However, the accuracy and limitations of these tools are still questionable. Validation with experimental findings could be a direct method to ensure the accuracy of the method. On the other hand, such validations may not be applicable in many related engineering problems. Therefore, it is essential to understand the limitations of the computational methodology at hand. A FCG simulation might be even more complicated in the presence of other effects that exists in real life examples. Residual stresses that might occur as the result of a welding process is one of such effects. To compute the effects of residual stresses on fracture problems, a new methodology was developed and proposed recently [1]. Current study extends that methodology by using fracture analysis techniques (Virtual Crack Closure and Displacement Correlation) for crack propagation and making related comparisons. Flaws in T-joints in the form of semicircular cracks and cracking in weld toe are examined with the aid of finite element methods. It was seen that the solution methodology along with selected element type might influence the nature and behaviour of crack growth simulation. If residual stress effects are added to this overall problem, then the fracture results become more complicated to comment on. Solutions for the current problems will be accompanied by the verification examples. REFERENCES [1] M. Saribay.
