The Biomechanics Research Centre (BioMec) at NUI Galway is seeking applications for a funded-PhD position in Multiscale Mechanics of Bone Fragility in Type-2 Diabetes for a project funded by the European Research Council Starter Grant Scheme, under the supervision of Dr. Ted Vaughan (Google Scholar).
Here you find a response to the MCD paradox from McMeeking, M.Ciavarella, G.Cricrì, and KS Kim. Here.
The paper is dedicated to number one of Mechanical engineering in the world, John Hutchinson from Harvard.
Transverse wrinkles usually occur in a uniaxially tensile elastic membrane and will be smoothed upon excess stretching. This instability-restabilization response (isola-center bifurcation) can originate from the nonlinear competition between stretching energy and bending energy. Here, we find a crucial factor, the curvature, which can control effectively and precisely the wrinkling and smoothing regimes. When the sheet is bent, the regime of wrinkling amplitude versus membrane elongation is narrowed, with local wrinkling instability coupled with global bending.
Just submitted a paper on electroadhesion of rough surfaces, greatly simplifying the recent theory of the great Bo Persson , with hot application to touch screens : see here.
Comments welcome.
Job Description:
The Department of Mechanical Engineering at the State University of New York at Binghamton invites applications for a tenure-track faculty position in solid mechanics at the assistant professor level beginning Fall 2020. Candidates must have a PhD in Mechanical Engineering or a closely related field.
Mechanics of crumpled materials
Crumpled materials exhibit unusual and as yet unexpained mechanical properties. Through the surprisingly complex morphologies of facets and ridges formed in the crumpling of paper into a ball or densser materials, very high strength to weight ratios can emerge.
The microMechanics of Deformation Research Group (mMOD) in the Department of Materials Science and Engineering at Rutgers University is seeking a Post-Doctoral Associate to participate in a pair of collaborative projects with a Department of Energy National Laboratory. The projects are focused on using discrete dislocation dynamics (DDD) simulations to understand dislocation patterning in deformed metals, and molecular dynamics (MD) simulations to understanding crack initiation in hydrogen-affected steels.
Fracture mechanics of porous materials
https://doi.org/10.1016/j.engfracmech.2015.10.004
The effects of pore geometry on fracture mechanics is studied by considering notches of various types with a uniform crack growth. This work, published in Engineering Fracture mechanics, sheds light on the role of stress concentrators in the toughness of porous materials.
