The influence of inclusion on crack Stress Intensity Factor(SIF) of Powder Metallurgy(PM) FGH 95 was investigated using singularelement method with fine mesh at crack front.
The stiffness matrix of a hybrid crack-tip singularelement is first derived, then by use of first-order Taylor expansion the mean and variance of stress intensity factors are formulated.
