Elastic stability of a compressed cantilever beam on an elastic foundation, with application to a dual-coated fiber-optic connector

A simple, easy-to-use and physically meaningful predictive analytical (mathematical) model is developed for the evaluation of the critical (Euler) force for a cantilever beam supported by an elastic foundation, with application to a dual-coated fiber-optic connector. The obtained results can be used in the stress analysis and physical (mechanical) design of such connectors. These results can be used also beyond the optical engineering field, when there is a need to evaluate the elastic stability of a cantilever beam supported by an elastic foundation.
