The default k factor is 0 44 which simply means that inventor is assuming that 44 through the cross section of the part the material is not stretched or squashed when bending and therefore this slice of the folded part will give the true length of the flat pattern.

So if the thickness of the sheet was a distance of t 1 mm and the location of the neutral axis was a distance of t 0 5 mm measured from the inside bend then you would have a k factor of t t 0 5 1 0 5.
