Interaction of Sustained Vortex Shedding with a Phononic Subsurface: Effect of Positioning and Resonant Characteristics
Sangwon Park, Vinod Ramakrishnan, Arturo Machado Burgos +2
Phononic materials (PMs) have emerged as a promising candidate to passively and beneficially interact with unsteady flows. However, their fluid-structure interaction (FSI) with sep…
On the effective magnetostrictive properties of anisotropic magneto-active elastomers in the small-deformation limit
Connor D. Pierce, Kathryn H. Matlack
Magneto-active elastomers (MAEs) are composite materials comprising an elastomer matrix with embedded magnetic particles, endowing the composite with coupled effective magneto-mech…
