Incremental Sheet Metal Forming Simulation

One step a single step calculation that completes very quickly in one step.

Incremental sheet metal forming simulation.

Simulation of single point incremental forming spif in catia v5. Two broad divisions in the application of finite element analysis method for sheet metal forming can be identified as inverse one step and incremental. Incremental simulations yield all the relevant parameters that interest the forming expert from strain distribution sheet thickness and cracks for example to springback in the trimmed part stress distribution and hardening. In the present paper deformation behavior of sheet metal in an incremental forming process is numerically simulated using a dynamic explicit finite element code dyna3d halliquist 1989.

Inverse one step methods compute the deformation potential of a finished part geometry to the flattened blank. Within each step or increment the positions velocities accelerations and forces are calculated at the nodal points in the blank. However isf does not require any dedicated tool. The dimple was drawn and through our simulation we were able to successfully reduce the process to six steps in order to minimize the thinning percentage to the required level.

It is important to understand the difference between the two calculation methods and to understand when it is appropriate to use each method. In conventional forming process the products are produced by dedicated tools i e. Hence with these methods it is possible to optimize the tool as well as the component. The forming process simulations were successful in eliminating forming problems splits wrinkles and other negative outcomes before the tooling was designed and manufactured.

The term incremental and one step refers to the calculation method used to solve the forming simulation mathematics of a sheet metal forming simulation problem. Because this is a dynamic code mass of the material and the deformation speed affect the deformation behavior. 13 3 3 incremental forming analysis. Incremental sheet forming isf process is an advanced flexible manufacturing process to produce complex 3d products.

This video will show you how to perform simulation of single point incremental forming spif in catia v5.
