Hi,

I have obtained the factor for the curved rectangular plate by referring to this correction factor formula from DNV GL for curved plates, that can be used for thickness reduction of plate.

Fr = 1-(b/2*r) 'b' - Arc length, r- Radius

But, I need to calculate the factor from the results of FEM analysis by considering its stress and other parameters of the curved plate like radius, length and thickness. So, it would be great if someone can refer other method / formula which can be used for curved plate to obtain the factors.

Thank you
