Sentence:  The <WSD>spew</WSD> is represented by a triangular fillet 0.5 mm high. It can be seen that, because of the predominance of the major principal stress, the adhesive at the ends of the adhesive layer and in the <WSD>spew</WSD> fillet is essentially subjected to a tensile load at about 45° to the axis of loading. The highest stresses occur within the <WSD>spew</WSD> at the corner of the unloaded adherend, the presence of the 90° corner introducing a stress-concentration effect. 
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.
