Paper: Swelling effects on the adhesion
Swelling effects on localized adhesion of an elastic ribbon M. Curatolo , P. Nardinocchi , L. Teresi and D.P. Holmes Proceedings of the Royal Society A, 475(2225), 0067, (2019) Abstract: We investigate the adhesion mechanism between an elastic strip of vinylpolysiloxane bent in a racquet-like shape, and a thick elastomeric substrate with the aim to […]
Review Paper: Elasticity and Stability of Shape-Shifting Structures
Elasticity and Stability of Shape-Shifting Structures Douglas P. Holmes Current Opinion in Colloid and Interface Science, 40:118-137, (2019). Abstract: As we enter the age of designer matter — where objects can morph and change shape on command — what tools do we need to create shape-shifting structures? At the heart of an elastic deformation is […]
Paper: Buckling of geometrically confined shells
Buckling of geometrically confined shells Lucia Stein-Montalvo, Paul Costa, Matteo Pezzulla and Douglas P. Holmes Soft Matter, 15(6), 1215-1222, (2019). Abstract: We study the periodic buckling patterns that emerge when elastic shells are subjected to geometric confinement. Residual swelling provides access to range of shapes (saddles, rolled sheets, cylinders, and spherical sections) which vary in […]
Paper: Snapping of bistable, prestressed cylindrical shells
Snapping of bistable, prestressed cylindrical shells Xin Jiang, Matteo Pezzulla, Huiqi Shao, Tushar K. Ghosh, and Douglas P. Holmes, Europhysics Letters (EPL), 122, 6, (2018). Bistable shells can reversibly change between two stable configurations with very little energetic input. Understanding what governs the shape and snap-through criteria of these structures is crucial for designing devices […]
Paper: Elastogranular Mechanics
Elastogranular Mechanics: Buckling, Jamming, and Structure Formation David J. Schunter, Jr., Martin Brandenbourger, Sophia Perriseau, and Douglas P. Holmes, Physical Review Letters, 120, 078002, (2018). Confinement of a slender body into a granular array induces stress localization in the geometrically nonlinear structure, and jamming, reordering, and vertical dislodging of the surrounding granular medium. By varying […]
Paper: Curvature-Induced Instabilities of Shells
Curvature-Induced Instabilities of Shells Matteo Pezzulla, Norbert Stoop, Mark P. Steranka, Abdikhalaq J. Bade, and Douglas P. Holmes, Physical Review Letters, 120, 048002, (2018). Induced by proteins within the cell membrane or by differential growth, heating, or swelling, spontaneous curvatures can drastically affect the morphology of thin bodies and induce mechanical instabilities. Yet, the interaction […]
Paper: Extended Lubrication Theory
Extended lubrication theory: improved estimates of flow in channels with variable geometry Behrouz Tavakol, Guillaume Froehlicher, Douglas P. Holmes, Howard A. Stone, Proceedings of the Royal Society A, 0234, (2017). Abstract: Lubrication theory is broadly applicable to the flow characterization of thin fluid films and the motion of particles near surfaces. We offer an extension […]
Paper: Kirigami Actuators
Kirigami Actuators Marcelo A. Dias, Michael P. McCarron, Daniel Rayneau-Kirkhope, Paul Z. Hanakata, David K. Campbell, Harold S. Park and Douglas P. Holmes, Soft Matter, 13, 9087-9802, (2017). Abstract: Thin elastic sheets bend easily and, if they are patterned with cuts, can deform in sophisticated ways. Here we show that carefully tuning the location and […]
Paper: Generalized Scaling Law of Adhesion
Revisiting the generalized scaling law for adhesion: role of compliance and extension to progressive failure Ahmad R. Mojdehi. Douglas P. Holmes. David A. Dillard, Soft Matter, 13, 7529-7536, (2017). Abstract: A generalized scaling law, based on the classical fracture mechanics approach, is developed to predict the bond strength of adhesive systems. The proposed scaling relationship […]
Paper: Friction of extensible strips
Friction of extensible strips: An extended shear lag model with experimental evaluation Ahmad R. Mojdehi. Douglas P. Holmes. David A. Dillard, International Journal of Solids and Structures, 124, 125-134, (2017). Abstract: The role of effective axial compliance on the frictional response of extensible strips is investigated, both experimentally and theoretically. A translational actuator pulled a […]
