This paper will research the singularity strength theory to stress distribution of a 135-degree sheet corner which bases on notch stress intensity factor (N-SIF) theory. The N-SIF formula is simplified through singularity strength 'as' which is related to structure size. Numerical simulations by ANSYS and regression analysis by MathCAD are done for a number of cases. Finally a simple assessment algorithms and the empirical formula for the notch stress are proposed and verified. The results can be used for structural strength and fatigue analysis.
