V Bending
sheet and beam bending
Estimate press force and plastic strain for V-die air bending and three-point bending at once, and run an FEA to see springback.
Product pages are in English.

Highlights
- Instant estimate from Gaussian-process models fitted to 200 large-deflection FEA runs, with a 95 % band
- Peak force, plastic strain and contact pressure or von Mises stress, with cross-validated accuracy
- Run FEA in the browser: finite-strain plasticity, frictional tool contact, loading and unloading
- Bend shown frame by frame with springback, contours and the difference from the estimate in %
- Save and reopen your inputs on your computer or in your cloud
A question it answers
How much press force does a 2.5 mm sheet need in a 16 mm V die with a 2 mm punch radius, and how much does it spring back?What you put in
V-bend: sheet thickness, V opening, punch radius, friction, yield stress, tangent modulus, stroke and part depth. Three-point: beam height, support distance, roller radius, friction, yield stress, deflection and beam width. FEA quality Draft / Standard / Fine; plane stress or plane strain for three-point.
What you get
Peak force (scaled to the part depth or beam width), maximum plastic strain, contact pressure or von Mises stress with their cross-validated accuracy, the force–displacement curve, an animated bend; after Run FEA the deformed mesh frame by frame with PEEQ or von Mises, contact pressure bars and force arrows per tool, the FEA curve against the estimate and the difference in %.
