Applications are invited from suitably qualified candidates for a full-time, fixed term Postdoctoral Researcher position on computational mechanics of biodegradable medical devices at the Biomechanics Research Centre (BioMec) NUI Galway. This position is funded through a European Union Horizon-2020 project, ‘InSilc’ (In-silico trials for drug-eluting bioabsorbable vascular scaffold development and evaluation), and and are available from 1^st May 2019 to the 31^st October 2020.

Adhesion is a key factor in many tribological processes, especially wear. We generalize a recent formulation for the indentation of a multilayered material using an efficient integral transform method, to the case of adhesion, using a simple energetic transformation in the JKR regime. Then, we specialize the study for the geometry of the Surface Force Apparatus, which consists of two thin layers on a substrate, where the intermediate layer is softer than the other two. We find the pull-off force under "force control" (i.e.

The Department of Mechanical and Aerospace Engineering in the School of Engineering and Applied Science at the University of Virginia seeks candidates for a Research Associate to assist in the development of low-cost carbon fiber techniques in Professor Xiaodong (Chris) Li's lab.

Formation of solidification defects and their evolution in uniaxial tensile deformation of solidified polycrystalline aluminum (Al) were investigated by molecular dynamics (MD) simulations. First, solidification process was simulated both isothermally and with different quench rates. At the initial stages of nucleation, coherent twin boundaries and/or fivefold twins formed depending on the quench rate or the undercooling temperature. The solidified polycrystalline Al consisted of randomly distributed grains, twin boundaries, and vacancies.

There are immediate openings for candidates in the areas of computational solid mechanics and experimental (bio)mechanics in the mechanical engineering department, University of Illinois at Chicago (UIC). 

Candidates with strong background in numerical simulations (FEA, high performance computing, ...), in experimental characterization of materials, or biochemistry and molecular biology are encouraged to apply. 

In this paper we formulate the problems of nonlinear and linear elastodynamic transformation cloaking in a geometric framework. In particular, it is noted that a cloaking transformation is neither a spatial nor a referential change of frame (coordinates); a cloaking transformation maps the boundary-value problem of an isotropic and homogeneous elastic body (virtual problem) to that of an anisotropic and inhomogeneous elastic body with a hole surrounded by a cloak that is to be designed (physical problem).
