Paper: Curvature-driven morphing of non-Euclidean shells
Curvature-driven morphing of non-Euclidean shells Matteo Pezzulla, Norbert Stoop, Xin Jiang, Douglas P. Holmes, Proceedings of the Royal Society A, 473(2201), (2017). Abstract: We investigate how thin structures change their shape in response to non-mechanical stimuli that can be interpreted as variations in the structure’s natural curvature. Starting from the theory of non-Euclidean plates and […]
Paper: Elastogranular Buckling
Buckling of elastic beams embedded in granular media Ahmad R. Mojdehi, Behrouz Tavakol, Wesley Royston, David A. Dillard, Douglas P. Holmes, Extreme Mechanics Letters, 9, 237–244, (2016). Abstract: In this paper, an experimental and theoretical study of the buckling response of slender elastic beams within granular media is performed. Buckling loads of beams with different […]
Paper: Elastocapillary Swelling
Rising Beyond Elastocapillarity Douglas P. Holmes, P.-T. Brun, Anupam Pandey, and Suzie Protière, Soft Matter, 12, 4886-4890, (2016). Abstract: We consider the elastocapillary rise between swellable structures using a favorable solvent. We characterize the dynamic deformations and resulting equilibrium configurations for various beams. Our analysis reveals the importance of the spacing between the two beams, […]
Paper: Growing sheets into shells
Geometry and mechanics of thin growing bilayers Matteo Pezzulla, Gabriel P. Smith, Paola Nardinocchi, and Douglas P. Holmes, Soft Matter, 12, 4435-4442, (2016). Abstract: We investigate how thin sheets of arbitrary shapes morph under the isotropic in-plane expansion of their top surface, which may represent several stimuli such as nonuniform heating, local swelling and differential […]
Paper: Buckling with fluid electrodes
Voltage-induced buckling of dielectric films using fluid electrodes B. Tavakol and D.P. Holmes, Appl. Phys. Lett., 108, 112901, (2016). Abstract: Accurate and integrable control of different flows within microfluidic channels is crucial for further development of lab-on-a-chip and fully integrated adaptable structures. Here, we introduce a flexible microactuator that buckles at a high deformation rate […]
Paper: Growing Sheets into Shells in Soft Matter
Our manuscript entitled “Morphing of geometric composites via residual swelling” has been published in the Soft Matter. This work was authored by Matteo Pezzulla, and co-authored by Steven Shillig, Paola Nardinocchi, and Douglas Holmes. This work was also highlighted on Soft Matter’s inside cover: Understanding and controlling the shape of thin, soft objects has been […]
