Ring rolling

FORGE predicts the local deformation, temperature, stresses, strain rate and other typical FORGE results. With this information, it is possible to predict the final part characteristics after heat treatment (grain size, hardness, ….).

The inputs required for the ring rolling simulation are ring material, process description, tool design and rolling machine parameters.

The GLPre pre-processor in FORGE uses a specific ring rolling project template. This means that the user can easily setup a ring rolling simulation in a matter of minutes. The template includes the ring, the king roll and its rotation speed, the mandrel and its radial speed or load. Axial rolls can also be included in the simulation.

Rectangular and contoured cross section rings can be simulated. The ring rolling simulation can be hot, warm or cold, and involve any type of metal.

Bar shearing

This example shows the cold shearing of a bar. In this application, the most important results provided by FORGE are the press load and how the shearing progresses.

At the end of the simulation, FORGE predicts the shape of the sheared surface and the residual stresses.

Punching and trimming

FORGE is used to evaluate the deformation of the part which is created during the piercing process.

Coupled die computations

Coupled die analysis is illustrated on the following automotive application. FORGE has enabled the simulation of a complex tool stack made of 8 different deformable dies.

Stresses are computed inside each die.
