Performance of normalization method for steel with different strain hardening levels and effective yield strengths

Normalization method is more convenient than unloading compliance method in determining J-resistance (J-R) curve and fracture toughness of steel. However its performance has not been evaluated for different types of steels. Experimental tests are undertaken and analytical studies are carried out in this work to determine the J-R curves and fracture toughness of various steels using the normalization method, including Weldox700, G350 and G250,...
