Abstract: An experimental study of the effects of warm prestressing on the fracture strength of notched and fatigue-cracked bend bars of a Ni-Cr-Mo, low-alloy forging-grade steel was conducted. The steel ...

Abstract: A testing program has been run using off-centered-cracked (OCC) plate specimens to demonstrate the fracture characteristics of tunnel defects in specimens with various ligament lengths between the ...

Abstract: Fatigue-crack growth rates were determined at room temperature for ASTM A302-Class B and A 508-Class 2 steels in two characteristic plate and forging directions. Tests were performed under ...
