Break it ’til You Make It: Engineering Shapes and Patterns
Gordon Current Science & Technology Center Stage, Blue Wing, Level 1
Saturday, August 26; 12:30 pm
Abstract: Not long ago, a structure losing stability led to failure and disaster. Instability makes rigid materials useless, so it was something that engineers had to design around. Soft materials, like rubbers, plastics, and gels, however, can bounce back from instability. The resilience of soft materials has enabled scientists to rethink the role of stability in the design of new materials. Douglas Holmes, an assistant professor of mechanical engineering at Boston University, explores the instabilities that cause skin to wrinkle, roots to tangle, toy poppers to jump, and we will discover how engineers design wearable electronics, make smart needles, and create ultra lightweight mechanisms.

MOSS@Adhesion Society
The MOSS lab presented research by Anupam Pandey, done in collaboration with Suzie Protière, at the 2015 Annual Meeting of the Adhesion Society in Savannah, GA. The talk was entitled "Elastocapillary Rise Between Swellable Beams", and was presented in the “Soft III: Mechanics” track (More details)

Seminar: Center for Materials Processing and Tribology: Morphing of Slender Structures by Swelling - Prof. Douglas P. Holmes
February 4th, 2015
Abstract:
Swelling-induced deformations of slender structures occur in many biological and industrial environments, and the shapes and patterns that emerge can vary across many length scales. The dynamics of fluid movement within elastic networks, and the interplay between a structure's geometry and its boundary conditions, play a crucial role in the morphology of growing tissues, the shrinkage of mud and moss, and the curling of cartilage, leaves, and pine cones. This talk will examine the geometric nonlinearities that occur as slender structures are swollen – surfaces will crease, beams will bend and snap, circular plates will warp and twist, and fibers will coalesce and detach.
