Three-dimensional vibration of a buckled elastica supported by spherical hinges.

Highlights: [•] Director theory is used to formulate the equations of motion. [•] Shooting method is adopted in the numerical analysis. [•] Focus is placed on the effects of extensibility on the vibration characteristics. [•] The results from extensible elastica, inextensible elastica, and small-deformation theory are compared.
