Research at University of Bristol:
The research undertaken focuses on adaptive structures, with a strong interest for aerospace applications, example of which are morphing surfaces for load control (morphing flaps, twisting wing tip) and deployable structures (deployable boom for spacecraft, nature inspired lattice structure). Particularly, zero stiffness structures are of interest for their minimum actuation cost while removing the need for joints and mechanisms.
