Use this calculator to determine behaviour and mechanical properties of a snap-fitting hook or cantilever snap with ring shaped cross section. Calculate
deflection force, mating force and maximum strain as a result of a given
deflection and geometry
h, L, b, α. Alternatively one can calculate the thickness
h required for the given
deflection and the permissible strain
εpm.
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.
