Determination of Stress Distribution in Crane Hook by Caustic
نویسنده
چکیده
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 ABAQUS software. Real time pattern of stress concentration in 3D model of crane hook is obtained. The stress distribution pattern is verified for its correctness on an acrylic model of crane hook using shadow optical method (Caustic method) set up. By predicting the stress concentration area, the shape of the crane is modified to increase its working life and reduce the failure rates.

Abstract: Crane hook is a curved beam. Hooks are employed in heavy industries to carry tones of loads safely. These hooks have a big role to play as far as the safety of crane loaded is concerned. With more and more industrialization the rate at which these hooks are forged are increasing. This project is carried out to study the stress variation in crane hooks for different cross sections such...

Stress analysis plays a significant role in the design of parts and structures that must carry load [1]. In this study, Crane hook which is one of lifting equipment, frequently used in material handling is investigated. Analytical (Straight beam, curved beam & Winkler-Bach approximation), experimental (Photo-Elasticity) and numerical (FEM) methods were used by various researchers to study stres...
