چکیده انگلیسی
The effect of material viscoelasticity on the stability of structures is investigated. It is demonstrated that viscoelastic effects can cause structures to exhibit temporary bistability in a deformed configuration. When this bistability is lost, the structure may suddenly jump back to its initial configuration in a phenomenon described as self-actuated snap back. It is shown for both a single degree of freedom system and a hemispherical cap that the viscoelastic behaviour may be inferred by consideration of the purely elastic response. These inferences are confirmed by means of finite element analysis.
