Fracture toughness of C-Mn (A516-70) steel weld metal / Borhannudin Mohamad and Ismail Omar

The development of yielding fracture mechanics techniques has opened up the possibility of defining the levels of toughness required to minimise the risk of brittle fracture. Approach of the fractures toughness of weldments is influenced by the preparation of welded test panels. The approach given p...
