- Two noncorresponding mesh techniques that augment the finite element method are developed for the analysis of stress raisers in solid structures. Both work by tying the boundaries of a refined mesh at a stress raiser to the coarse displacement field of the surrounding structure. Algorithms are presented that utilize isoparametric shape functions to express the refined mesh boundary displacements as a function of the coarse mesh displacements. Stress concentration factors for two common stress raisers are calculated, using both methods, and compared to accepted values.
