Dynamic Morphing of Actuated Elastic Membranes
Parametric resonances of elastic membranes actuated by harmonic in-plane strains prescribed along given directions are exploited to drive dynamic morphing of lightweight, flexible panels employed in engineering applications which require active, shape-changing surfaces. An approximate nonlinear model of a pretensioned membrane together with its Galerkin discretization are adopted to describe the membrane out-of-plane motion.
