Abstract

Dimpled steel products are formed by dimpling process and cold rolling process. Nowadays, a wider use of dimpled products is seen due to increased strength and life of these products. In this study, dimple sheet analysis is done using the theoretical, experimental and software simulation. First, the single dimple is theoretically analyzed using Hertz contact theory and then compared to ANSYS results. A reference 3D Finite Element model of the single-step stamping is established, and the corresponding stress results are obtained. The Finite Element solutions are obtained for two materials stress values. Secondly, the multipoint analysis is done using ANSYS and by experiment. Then, a 3-point bending test is also carried out to check the stress and deflection values for different materials. The result shows that the strength of the dimple sheet is higher compared to the plain sheet due to the non-linear shape. Finally, all results are analyzed and compared in this paper.
