- Sheet metal forming by numerical simulations: 2D and 3D axisymmetric deformation of a cylindrical piecePublication . Mouta, K.; Azevedo, Lucas D.; Fernandes, M.G.A.; Fonseca, E.M.M.The aim ofthis work is conduct numerical simulations to verify the deep drawing process and the shape of the final stamping component of a simple profíle of a sheet metal geometry. To evaluate the design of sheet metal forming, ANSYS program was used. A nonlinear dynamic explicit numerical model was developed using two different models: a 3D quarter aad a 2D axisymmetric fínite element model, due the geometry and loading conditions symmetry to reduce the computational time processing. reduce the computational time processing.
- Sheet metal forming by numerical simulations: 2D and 3D axisymmetric deformation of a cylindrical piecePublication . Mouta, K.; Azevedo, Lucas D.; Fernandes, M.G.A.; Fonseca, E.M.M.Until few years ago, design of sheet metal forming was based on knowledge through work experience and expensive trial and error process. Nowadays the use of numerical simulations in different phases of the sheet metal forming process are performed using finite element analysis (Ranganath et al, 2012). Different codes are available for finite element analysis in metal forming such as Abaqus, Dynaform, Nike 2D, Ansys, etc. Deep drawing is the metalworking process used for stamping flat sheets into cup-shaped forms, where the metal is subjected to different types of deformations (Dieter, 1961). The aim of this work is conduct numerical simulations to verify the deep drawing process and the shape of the final stamping component of a simple profile of a sheet metal geometry. To evaluate the design of sheet metal forming, a nonlinear dynamic explicit numerical model was developed using two models: a 3D quarter and a 2D axisymmetric finite element model, due the geometry and loading conditions symmetry to reduce the computational time processing. The numerical simulations showed the shape deformation occurring after start the process and provided detailed quantitative information about expected weakness of the resulting piece.
