A Review on FE Analysis, Simulation and Optimization of Sheet Metal Forming Process - A FE, DOE And Statistical Approach

In Sheet metal forming process materials undergo permanent deformation by cold forming to produce a variety of complex three dimensional shapes. The process is carried out in the plane of sheet by tensile forces with high ratio of surface area to thickness. High rate of production and formability is determined by its mechanical properties. Methods of sheet metal processes such as stretching, shearing, blanking, bending, deep drawing, redrawing are introduced. Variables in sheet forming process were discussed together with formability and test methods. Defects occurring during the forming process will be emphasized. The solutions to such defect problems will also be given. the detailed of literature review is presented in this paper corresponding to the metal forming processes and the various methods used for the analysis and optimization for defect free process are explained. As lots of research is going in the field of material forming a systematic literature review based on the optimization technique and analysis is presented in the paper.
