Sheet metal folding
Sheet metal folding
(OP)
Hi,
I would like to know if there is a relation or formula that governs the folding of a sheet metal taking into consideration the plate thickness, material, and bending angle. Stress and strain must be included in the formula. More particularly, I'm interested in folding a plate to form a U-bar.
Thanks for your help.

But what do you mean by "quarter hard or softer" when folding a material? By the way, we are using steel.
Thanks.

1) quarter hard temper, and bending axis MUST be perpendicular to the grain direction and (bending radius >= stock thickness) , for this material to be bent parallel to the grain size, it's advisable to maintain at 90 degree right angle the most.
2) Skin rolled temper, basically a grade which is suitable for fairly deep drawing operations where surface disturbances such as stretcher strains are objectionable. It cane be bent in direction.
3) dead soft temper, a very soft and ductile cold rolled strip, it is suitable for bending flat upon itself in any direction.
Stress relief can be applied after the bending process if necessary.
