WebFeb 13, 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 the standard linear solid as the viscoelastic constitutive law, and is applicable to shells …
WebAug 22, 2024 · Mechanical metamaterials made of flexible building blocks can exhibit a plethora of extreme mechanical responses, such as negative elastic constants, shape-changes, programmability, and memory. To date, dissipation has largely remained overlooked for such flexible metamaterials. 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
