- Springback prediction
- Thinning and thickness
- Wrinkling and cracks
- Trim line prediction
- Clamp simulation
- Die and process optimization
Application areas
- Automotive body parts
- Stamping components
- Press forming
- Die development
- Sheet metal manufacturing
Engineering benefits
- Reduce die tryout
- Optimize the forming process
- Reduce material waste
- Improve product quality
Technology
Solvers
Built on the explicit and implicit solutions of LS-DYNA, with the JOH/NIKE implicit solver and the HYSTAMP one-step inverse solver for quick early-stage checks.
Springback
Supports the Yoshida-Uemori material model for high-strength steel and aluminium, plus springback compensation tools that reduce die correction rounds.
Crack evaluation
Beyond FLD: the optional JESOLVA-Forming package adds 3D-FLD, stretch-flange crack and delayed fracture prediction, shown in the post-processor.
Advanced processes
Hot forming analysis, solid-element sheet models with several layers through the thickness, and an interface for CFRP press forming with Digimat.
