Metal Forming Optimization
This example illustrates an optimization of a metal forming process with LS-OPT.
Forming
Trimming
Springback
This example problem illustrates the following features:
- Setting up a process consisting of several simulation steps in LS-OPT.
- How variables in the first stage affect responses in final stage in process.
- File transfers between stages.
The criteria of interest are the following:
- Springback of final component.
- Thinning of metal sheet.
Design formulation:
- The variables are the starting and ending binder force, linearly varying in between.
Conclusions:
- LS-OPT easily facilitates influence studies of process variations, introduced at any stage in the process, on the final component.
