Morphing multistable structures is treated as computationally complex smart structures, which can show reconfigurable stable configurations for the changes in surrounding loads. Shape morphing structures exhibit various equilibrium stable shapes and require actuation energy for the shape transition during its structural performance. The major geometries of individual unsymmetric laminates studied so far were either rectangular or square. This paper attempts to study the behaviour of bistable shapes obtained from triangular shape unsymmetrical composite laminates for morphing applications. Snap through between the simulated bistable shapes is obtained by applying a transverse point load on the surface of the laminate. A detailed parametric study is performed to identify the effect of geometrical parameters on the snap‐through force of triangular laminates. All numerical investigations are performed using a commercially available finite element software, Abaqus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
