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 […]

Twitter: Elastocapillary Swelling
What happens when you dip two rubber beams into a bath of oil? Something very bizarre… https://t.co/PRCuCOW6XH pic.twitter.com/JJpjI4mgqF — Douglas Holmes (@dpholmes) June 1, 2016
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 […]
