The Interaction of Weld Defects under Plastic Collapse

Abstract:

Article Preview

Multiple defects in welds, when detected, have to be assessed for interaction. Current code rules are based on linear elastic fracture mechanics whereas the failure mode for welds in thin structures is primarily plastic collapse. Results of large-scale tests illustrate that current interaction rules have a high degree of conservatism for plastic collapse conditions. Guidance for the assessment of defect interaction under plastic collapse is proposed.
