Crack Arrest Fatigue Hydrogen Assisted Crack Make Crack Harmless Overload Effect SCC
This study proposes an innovative method for arresting SCC, fatigue and hydrogen assisted cracks, and making harmless the cracks by overload. By overloading, compressive residual stress is introduced ahead of the crack. The residual stress reduce K values and arrest the crack. By theory, Kiscc, Kjhe and Kth increase with increasing Kov (K value by overload) and the nominal threshold values were given the equation: “Kuscc, NKjhe and NK th=C + D Kov. Where C is Kiscc, Kihe and Kth, respectively, and D is a p...
