NUMERICAL STUDY ON STRESS ANALYSIS OF CURVED BEAMS

The static analysis of naturally curved beams with closed thin walled cross section has many important applications in mechanical, civil and aeronautical engineering. Many of the curved beams subjected to bending moment find in real life applications .Due to bending moment, tensile stresses developed in one portion of the section and compressive stresses in other portion of cross section. The analytical computation to determine these stresses are more complex, therefore in this paper we attempted the determination of stresses and deflection of curved beams when it is subjected to bending moment with the help of ansys software. The result obtained from ansys software is validated with the simplified stress equations of curved beams developed by the other researchers. The material selected for curved beams for simulation studies is isotropic ductile material. The geometry of curved beams is described with central included angle in this paper. The work carried out exhaustively covers the estimation of stresses in quarter circle beam, semi circle beam, three quarter circle beam and full circle beam. The methodology adopted for simulation model briefed out step by step in this paper for further studies of other researchers
