Abstract:
The transferability of the toughness results in ductile-brittle
transition region for welded cracked specimens is conducted by
3D FE analysis. The fracture toughness values for the double edge
notched tension specimens are predicted effectively from the
bend test results based on the local approach considering stable
crack growth. It is found that the cell model gives a good
description of the stable crack growth behavior, and the local
approach is useful for the transferability analysis of fracture
toughness results in ductile-brittle transition region.
