Incremental Sheet Metal Forming Simulation

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 sheet metal forming simulation.

Hence with these methods it is possible to optimize the tool as well as the component. In incremental simulations the forming process is divided into steps or increments and the problem is solved incrementally through time. 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. One step a single step calculation that completes very quickly in one step.

It is important to understand the difference between the two calculation methods and to understand when it is appropriate to use each method. Because this is a dynamic code mass of the material and the deformation speed affect the deformation behavior. In conventional forming process the products are produced by dedicated tools i e. 13 3 3 incremental forming analysis.

Within each step or increment the positions velocities accelerations and forces are calculated at the nodal points in the blank. Inverse one step methods compute the deformation potential of a finished part geometry to the flattened blank. Unlike one step simulation in which only the final part shape is solved incremental forming simulation allows the accurate modeling of sheet forming processes.

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. Simulation of single point incremental forming spif in catia v5. 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.

The forming process simulations were successful in eliminating forming problems splits wrinkles and other negative outcomes before the tooling was designed and manufactured. This video will show you how to perform simulation of single point incremental forming spif in catia v5. Simulation makes it possible to detect errors and problems such as wrinkles or splits in parts on the computer at an early stage in forming.
