This chapter deals with several typical solutions to demonstrate effects of the mis-match factor, three-dimensional deformation (thickness effect) and plastic anisotropy on the limit load of welded plates. The general approach to build up singular kinematically admissible velocity fields previously used in plane strain and axisymmetric solutions for highly undermatched structures is extended to three-dimensional deformation of tensile specimens to estimate the thickness effect on the limit load. The effect of the mis-match factor on the limit load is illustrated by simple examples for overmatched and undermatched center cracked specimens in tension. The effect of plastic anisotropy on the limit load is demonstrated for both highly undermatched and overmatched center cracked specimens under plane strain conditions.
