... The dynamic fracture toughness of an ASTM A533, Grade B steel plate was determined at several temperatures in the ductile-brittle transition region. Crack-tip loading rates ranged from approximately 10 3 to 10 5 MPa√m/s. The fracture toughness was shown to decrease with increased loading rate...
