CTOD Fracture Toughness Test for Welded Joints of Steel
Abstract:
In order to ensure the enough fracture toughness for the thickness steel structure, based on DNV-OS-C401, using three point bending specimen with a center crack, the test of the typical bridge steel materials were carried out at 20°C. The CTOD value of base metal, heat affect zone and welded seam were obtained. The results show that the plastic displacement of the fracture toughness of the material plays a decisive role.
