Abstract

Dear iMechanicians,

https://pubs.acs.org/doi/abs/10.1021/acsbiomaterials.9b01983

Beta-sheet protein structures and domains are widely found in biological materials such as silk. These assemblies play amajor role in the extraordinary strength and unique properties of biomaterials.  In our new work, we employ simple Langevin-based models to investigate the behavior and the collapse of these structures.

This is the preprint of an article that will appear in Computer Methods in Applied Mechanics and Engineering (https://doi.org/10.1016/j.cma.2020.112946).

This is our recent work on the design of fatigue-resistant hydrogel adhesion. In this work, we show that fatigue-resistant hydrogel adhesion can be achieved by anchoring ordered nanocrystalline domains at the interface. This method is applicable to glass, ceramic, titanium, aluminum, stainless steel, and even elastomers including PU and PDMS. We also demonstrate its potential applications as endurant hydrogel coatings for versatile engineering materials with complex geometries.
