Modifying the drop weight tear test for tough pipeline steels

OSTI ID:7321927
In drop weight tear tests (DWTT), an abnormal fracture mode appears in some steels of high toughness, owing to a high fracture initiation resistance. A notch modification of the DWTT and an analytical method for estimating the crack-arrest fracture toughness from the fracture appearance were developed. Relations between K and shear fracture percentage were analyzed. (DLC)
