How to calculate the bending coefficient of sheet stainless steel?

The bending coefficient is closely related to the bending R, and there are specific calculation formulas.

The bending coefficient (z) of stainless steel plate is 0.2 ~ 0.3T, generally 0.25t.

The bending coefficient (z) of cold rolled steel sheet is as follows:

When t>3.0, the bending coefficient is 0.3 ~ 0.4t.

The bending coefficient of aluminum plate is 0.5T.

The bending coefficient of copper bar is 0.4t.
