New design of repair welded joints based on materials heterogeneity
Yield load solutions for the different strength mismatch welded components are given in the references, but they offer the expression for the yield load only in the case when the weld joint is homogeneous. The goal of this paper is to present the yield load solutions obtained by plane strain finite element analysis for most used fracture toughness specimen – single edge notch bend SE(B) specimen, which consists two different materials in the weld. The benefits of the approach where the one half of the weld is composed from the strength overmatch (OM) metal and the second half from the strength undermatch (UM) metal have been considered. Practical application of the weld component, where the crack tip can be located in the OM or UM weld part has been discussed. Obtained finite element mismatch yield load solutions in the form of diagrams will be compared with existing solutions in literature for homogeneous either overmatch or undermatch weld.
