Environmeutally assisted cracking (EAC) behavior is controlled by various parameters, which makes the experimental procedures very tedious for a overall understanding of the cracking process. In order to elucidate the effect of some of the most critical parameters on EAC, a theoretical tbrmulation has been developed and based on the numerical analyses, some of the mechanical, material and environmental parameters, those affect the cracking process significantly have been outlined. The effects of yield strength, strain hardening exponent, loading mode, state of stress
and repassiwttion kinetic behavior on the crack growth rate have been discussed based on the theoretical analyses. Experimental results of crack tip solution chemistry evaluation and passive film characterization have been discussed.
