A Review on Modeling and Analysis of Crack in the Sheet Metal Forming Process

All sheet metal forming processes occur after permanent plastic deformation resulting in the material properties variation and therefore it is necessary to determine the extent to which a material can further be deformed for subsequent forming. Normally tentative trial and error procedure was employed to determine these changes and adjust process settings (dies design parameter, loadings, tool course) accordingly. This approach is time consuming and depends heavily on the experimentation and trial. To concentrate on these limitations, sheet metal forming simulations has been applied to detect crack in sheet metal forming process. In this dissertation simulation is carried out on Ansys and Hyper form software, simulation result validation is carried out by experimentation process. By using sheet metal simulation, we can easily analyse the meshing conditions, stress analysis & failure point in sheet metal. After analysing the data, we can easily finalize the forming process parameter & experimentation which is the motive of this dissertation.
