Supramolecular assemblies are dynamic structures composed of simple molecular building blocks that self-assemble into hierarchically organized complexes driven by reversible (weak) intermolecular interactions (e.g. hydrogen bonds). This bottom-up approach to materials synthesis is utilized in nature to create flaw tolerant, highly functional materials that exhibit extraordinary mechanical properties arising from parallel clusters of weak interactions such as hydrogen bonds that work collectively. Such geometric arrangements are observed in stable biomolecular assemblies such as spider’s silk and amyloid plaques (see for instance an earlier journal club entry on protein materials http://imechanica.org/node/2653 ).

From a mechanical instability perspective, a double-eyelid is a double-folded thin film structure on a curved substrate, caused by compression as the film “slides” on the substrate. The underlying mechanics issues, in particular the requirements for forming a double-folded structure, are studied using a modeling/simulation framework. A minimalist model is employed to explore the wrinkle-to-fold transition. Refined and enriched models are further developed based on anatomical structures, which demonstrate three critical factors for the formation of double-layer folding of the eyelid. First, a crease line in the eyelid is essential where the local bending rigidity is relatively weak. Second, the skin above the crease line should be thin and wide enough. Third, the skin below the crease line should be possessed with relatively large effective stiffness so it can be lifted as a whole when eyes open. When the eye is opened beyond about 40% of its initial wrinkle wavelength, the double-folded structure emerges. Various types of eyelid morphologies are discussed based on the mechanistic model. The study provides useful insights for surgery, cosmetics, morphogenesis, as well as microfabrication.
Simulation of the double (up) and single (down) eyelid.
I have written a National Academy of Sciences biographical memoir of Zay Jeffries, one of the great American metallurgists of the 20th century. I am posting the link to the NAS website here with the thought that some readers of iMechanica might be interested in the piece. Some will be interested to learn that Jeffries came very close to discovering dislocations some 18 years before the great papers of Taylor, Orowan and Polyanyi in 1934.
A research position for a Postdoctoral Research Associate is now available at the working group of Continua Mechanics at the TU Darmstadt, Germany, led by Professor Dr.-Ing. Charalampos Tsakmakis.
The position is fulltime fixed-term for two years.
The main task is the development of a thermodynamical consistent constitutive model for micropolar and micromorphic
plasticity and its numerical implementation into a finite element environment. Preliminary work has been done, so that a
satisfactory closure is possible within the given scope of two years.
