Broderick Coburn, ACCIS DTC student
Broderick’s project, entitled The Venus Flytrap – A Bistable Orthotropic Shell Structure, explains the fast snapping mechanism of the Venus flytrap. This was shown by modelling the lobes as bistable layered structures accounting for orthotropy, doubly curved geometry and the biological actuation mechanism. Results show the Venus flytrap as a smart system which effectively switches on bistability to enable a fast snap and effective prey capture. This work was undertaken as part of Broderick’s six month research project which was supervised by Prof. Paul Weaver and formed part of the taught element of the DTC programme.
