Abstract
A buckled beam possesses two stable equilibrium configurations and is a natural bistable device. This paper first derives the exact critical load . QcrS for a hinged buckled beam when it is subject to a concentrated force . Q at the midpoint quasi-statically. In the case when the midpoint force is applied suddenly, the exact expression of a conservative dynamic critical load . QcrD is derived, which guarantees that snapping will not occur as long as . Q is smaller than this value. © 2011 Elsevier Inc.
