In this work, the structural response of a doubly curved orthotropic shell is tailored to achieve tristable geometries. This is done by varying both material properties and the Gaussian curvature of the surface profile. Tristability is predicted analytically, verified with finite element analysis and, for the first time, demonstrated experimentally. Predicted geometries of the tristable states are shown to compare well with experiment.

Abstract
In this work, the structural response of a doubly curved orthotropic shell is tailored to achieve tristable geometries. This is done by varying both material properties and the Gaussian curvature of the surface profile. Tristability is predicted analytically, verified with finite element analysis and, for the first time, demonstrated experimentally. Predicted geometries of the tristable states are shown to compare well with experiment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
