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 …

WebThe study of viscoelastic domes has mainly been limited to either experiments or finite element simulations. Recently, Gomez et al. [1] studied the stability and dynamics of a viscoelastic dome represented as a lumped parameter Von Mises truss. They analyzed the dynamics in the pseudo-bistable region using the method of WebThis phenomenon is called pseudo-bistability(Liu et al.,2024b;Brinkmeyer et al.,2012;Gomez et al.,2024;Urbach and Efrati,2024), and will be utilized to build metasurfaces with programmable spatiotemporal textural morphing. To quantify the phenomenon in FEA, we instantaneously imposed a pressure load Dp/m
