Multistable cantilever shells: Analytical prediction, numerical simulation and experimental validation

Publication date: 8 September 2018Source: Composites Science and Technology, Volume 165Author(s): Matteo Brunetti, Lukasz Kloda, Francesco Romeo, Jerzy WarminskiAbstractThe numerical and experimental validation of multistable behavior of cantilever shells is addressed. The design of the laminated composite shells is driven by a recently proposed semi-analytical shell model, whose predictions are verified and critically examined by means of finite element simulations and stability tests on two manufactured demonstrators. In addition, the influence of the main design parameters on the shells stability scenario is discussed. Despite its simplicity, the reduced model allows to depict a fairly faithful picture of the stability scenario; therefore, it proves to be a useful tool in the early design stages of morphing shell structures.
