Tension and bending loads applied were monotonically increased to a level causing relatively large scale yielding at the crack tip. The elastic-plastic analysis, assuming power-law hardening relationship and Mises yield criterion, was based on incremental plasticity theory.
Crack depth ranging from 2 to 40% of plate thickness were considered.
Two limiting crack configurations, plane strain edge crack and semi-circular surface crack in fillet welded T-butt plate joint, were analyzed using the finite element method. This paper describes an elastic-plastic fracture mechanics (EPFM) study of shallow weld-toe cracks.
