Calculations of the stress singularity in the vicinity of the tip of two bonded wedges are described. Plasticity in the near‐tip region is accounted for within the framework of the Ramberg–Osgood relation. It is shown that the singularity can be larger for two bonded wedges than for a single wedge, and figures are presented to indicate how the stress singularity depends on the relevant parameters.
