Snap-fitting hook, straight, any cross section


Use this calculator to determine behaviour and mechanical properties of a snap-fitting hook or cantilever snap. Calculate deflection force, mating force and maximum strain as a result of a given deflection and geometry h, L, b, α. .

The force calculations make use of the Secant Modulus Es alternatively called Tangent Modulus. It is the ratio of stress to strain at any point on the curve in a stress-strain diagrame of a material. Next to that the friction coefficient μ is needed. Remember that that it is higher if the same material is used.

In these calculations the counter part is considered rigid. h y L α F I A A A-A g 1 g 2
