Sheet Metal Springback: Through-Thickness Stress Model (2D)

2D cross-section companion to the 3D V-die bending simulator: integrates the elastic-plastic bending stress across the sheet thickness layer by layer to get the bend moment directly, then computes springback from elastic moment-curvature unloading — a different, independent method from the 3D sim's closed-form Gardiner formula.

This 2D cross-section simulator models the same V-die bending operation as its 3D counterpart — punch a strip down over a die radius, retract, watch it relax — but predicts the springback with an independent method: rather than the 3D sim's closed-form Gardiner cubic formula, it slices the sheet thickness into layers, computes the elastic-plastic bending stress in each one, numerically integrates those stresses into a real bending moment, and derives the elastic curvature recovery directly from that moment. A live stress ribbon shows the elastic core and the saturated plastic bands on either side of it, so you can see exactly which fraction of the cross-section is doing the work of holding the bend versus springing it back.
