TO EVALUATE THE DYNAMIC DUCTILE FRACTURE OF PIPELINE STEELS BY USING INSTRUMENTED DROP WEIGHT TEAR TEST

Derived from the hinge model for a single-edge notched bend specimen,a single specimen method to estimate CTOACof high strength and toughness pipeline steels has been established,by regression of load line displacement against the logarithmic ligament during crack extension. As to monitor the crack...
