Abstract

The need for better aircraft performance is increasingly prompting designers towards the realisation of morphing or shape-adaptable structural systems. One way to achieve this is to employ multistable composites elements. In this paper a square, curved bistable plate is studied. The finite element analysis provides the load-deflection characteristic of the bistable plate. A cubic expression is then fitted to this curve, and the equation of motion of the plate is reduced to a single-degree-of-freedom (SDOF) system which has the form of the Duffing equation for a double-well potential system. The dynamics of the plate are investigated using bifurcation diagrams and shows that the qualitative behaviour given by the measured response is predicted well by the simple SDOF model.
