COMPARISON OF STRESS BETWEEN WINKLER-BACH THEORY AND ANSYS FINITE ELEMENT METHOD FOR CRANE HOOK WITH A TRAPEZOIDAL CROSS-SECTION

Yogesh Tripathi, U.K Joshi

Abstract: Crane Hooks are highly liable components and are always subjected to failure due to the amount of stresses concentration which can eventually lead to its failure. To study the stress pattern of crane hook in its loaded condition, a solid model of crane hook is prepared with the help of CATIA (Computer Aided Three Dimensional Interactive Application) software. Pattern of stress distribution in 3D model of crane hook is obtained using ANSYS software. The stress distribution pattern is verified for its correctness on model of crane hook using Winkler-Bach theory for curved beams. The complete study is an initiative to establish an ANSYS based Finite Element procedure, by validating the results, for the measurement of stress with Winkler-Bach theory for curved beams.
