The use of metal springs is diverse. Depending on the basic function (force distribution, movement, installation), there is a preferred spring selection. Whether metal springs made of flat material or wire material, read here what is important when developing a
Blattfeder Berechnung

With the leaf spring or flat spring clamped on one side, the maximum bending stress, spring force, spring deflection (deflection), spring leaf thickness and spring rate can be calculated as follows. The bending stress increases linearly with the leaf spring
