Stress singularity transition of generic wedges due to nanoelement layers

The effect of a nanoelement interfacial layer on the stress singularity transitions of generic wedges is analyzed using the finite element method. The singularity transitions corresponding to changes in the vertical stiffness and the lateral stiffness of the nanoelement are examined. In general, high vertical stiffness and high lateral stiffness yield singularities close to those of wedges without nanoelements while low vertical stiffness and low lateral stiffness cause the elimination of the stress concentration. Under high vertical stiffness and low lateral stiffness the singularity is dependent on wedge shapes and the dependence is analyzed in terms of the constraint condition.
