Sentence:  For a <WSD>spew</WSD> corner configuration shown in Figure 2.2 with the adhasive modulus far smaller than the adherent modulus, the order of the stress singularity in the corner A and B can be obtained from the WIlliam's solution under plane strian condition, and it is given in Figure 2.3. It is clear that <WSD>spew</WSD> corner would be free of singulatirites when the fillet angle is less than a critical angle, which is dependent on the Poisson's ration of the adhesive. 
Meaning of the word marked with <WSD> tags:  Adhesive that is squeezed from a joint under pressure and held across the joint by a fillet, thereby strengthening the joint.
