Design and Stress Analysis 0 f Various Cross Section of Hook

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 as circular and square and for different radii of curvature as well, experimentally and theoretically. Experimentally, the loads are obtained for different crane hooks for 5mm elongation on UTM (Universal Testing Machine). And then the stresses induced in the crane hooks against the loads obtained from experimentation are also calculated theoretically using curved beam theory. Then the different crane hooks are modeled in Pro-E 2.0 and then analysis is done for modeled hooks using ANSYS 12.1 to find the stresses induced in the hooks. Then the stresses evaluated from curved beam theory and ANSYS12.1 are compared and conclusions are made
