Stress Distribution at the Stiffened Edges of a Thick Curved Flat Bar

The present paper focuses on the determination of stress distribution at the stiffened edges of a thick curved flat bar using a new computational elasticity approach. The bar is rigidly fixed at its one end and the two opposing curved edges are subjected to circumferential stiffeners. The corresponding stress field of the curved bar is obtained from the finite-difference solution of an elliptic partial differential equation of equilibrium in polar coordinate system. The analysis is carried out for two different conditions of loading at the bar end. The effect of bar aspect ratio on the state of stresses at the stiffened edges is also included in the present analysis.
