Just added this really nice illustration to the article on how contact binaries form -- nice work by James Tuttle Keane showing the value of art and science together. #STEAM

Our latest paper on concrete fracture highlighting particle morphology appears on Cement and Concrete Research, by PhD student Deheng WEI, a joint work between Engineering Sydney Uni, HEMI - Hopkins Extreme Materials Institute and NUS, through Sydney Uni Global collaboration award. DOI: doi.org/10.1016/j.cemc…

Miss Google scholar much.

#dailymechanician The world just lost Mark Robbins. The Hopkins physicist made important contributions to the understanding of contact, friction & adhesion. His work with Luan examined how continuum mechanics break down for nanoscale contact problems, owing to surface roughness.

Static friction might be an illusion made by the rotation of kinetic friction. See: Nakano & Popov, Phys. Rev. E 102, 063001 (2020). journals.aps.org/pre/abstract/1…

Shape of grains can influence the way how water moves inside a granular material, and this has been tested by 3D printing to well control grain shapes.
