What is Bending operation ?

Bending refers to the operation of deforming a flat sheet around a straight axis where the neutral plane lies. The disposition of the stresses in a bent specimen, is due to the applied forces, the top layers are in tension and bottom layers are in compression. The plane with no stresses is called the neutral axis. The neutral axis should be at the centre when the material is elastically deformed. But when the material reaches the plastic stage, the neutral axis moves downward, since the material oppose compression much better than tension.

How to Calculate Bending Force?

Bending Force calculator uses Bending Force = (Bending Die Constant*Bent Part Length*Ultimate Tensile Strength*Blank Thickness^2)/Width between Contact Points to calculate the Bending Force, Bending Force is required to deform and bend the component in the desired shape during a bending operation. Bending Force is denoted by F_B symbol.
