Abstract

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).

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.

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. 

The Additive Microstructure Engineering Laboratory (AddME Lab) in the school of Mechanical and Aerospace Engineering at NTU (Singapore) is a young, diverse, and interdisciplinary research group with interests in in-line microstructure control and assessment during selective laser melting (SLM) processes. In this framework, we are collaborating with the Institute of High Performance Computing under the Agency for Science, Technology and Research (A*STAR), to simulate the microstructure of metals produced during SLM.

Dear Colleagues, 

Please consider submitting abstracts to our mini-symposium at the 14th World Congress on Computational Mechanics (WCCM XIV), Paris, France. The abstract submission deadline is December 15, 2019.
