Pseudo-bistability of viscoelastic shells
WebMay 1, 2012 · We say that the structure is pseudo-bistable, because it remains in a nominally unstable equilibrium, before quickly moving away from it after a period of time. This time-dependent behaviour is introduced through the use of a viscoelastic material which triggers the transition between the states. WebJan 29, 2024 · We model and explain the mechanism of pseudo-bistability with a viscoelastic shell model. It combines the small strain, moderate rotation shell theory with …

WebMar 1, 2024 · The idea of pseudo-bistability is that when a structure is held in a configuration that is near (but just beyond) a snap-through threshold, just as a popper toy may be held inside-out, the change in stiffness associated with stress relaxation may cause the structure to appear bistable (i.e. an elastic structure with the same instantaneous …
WebIn these applications, pseudo-bistability means that the actuation needed to move the structure between di erent states can be applied for a shorter duration, which may lead to a signi cant reduction in the energy consumed (Santer, 2010).
