Fatigue Failure of an Eyeglass Frame

Application ID: 19059


In the search for weight reduction, the cross-section of an eyeglass frame is continuously reduced. The thin section over the nose transfers the entire load between the two halves. This example predicts the fatigue life using the combined Basquin and Coffin-Manson model when eyeglasses are subjected to bending.

This model example illustrates applications of this type that would nominally be built using the following products:
