Abstract
This report describes results of tests conducted on 350WT plate steel at high strain rates using a high energy modified Split Hopkinson Bar System (SHB). Compact tension specimens with a thickness of 12.7 mm of 350WT steel in both L-T and T-L orientations were fractured. These specimens contained either a fatigued or pressed crack. The results were conducted at -45, -30 and -15C. Stretch zone width and shear lip measurements were performed. Temperature transition curves for shear lip and stretch zone were obtained for this steel.
