Postdoc Position in Optimization, Metamodelling, and Statistical Analysis at McGill University

Submitted by Hamid.Akbarzadeh on Tue, 10/10/2017 - 04:06

One postdoctoral and/or one MSc/PhD position are available in the Bioresource Engineering Department of McGill University for January 2018. The postdoctoral researcher and MSc student will work on a multidisciplinary research project involving Metamodeling, Optimization, Statistical analysis, and Numerical multiscale simulation to develop a predicative mathematical-computational model to analyze statistical biological data and to simulate transport phenomena in porous biological media. The candidate will work under the supervision of Dr. Hamid Akbarzadeh at McGill University.

Derivatives of Tensors

tensors

Hi all,

I am looking for a general definition of the derivative of a tenorial product (e.g. when the expression for Stress contains nonlinear terms in deformation gradient, F ).

I start with a very simple example:

∂F_pq/∂F_mn = δ_pm δ_qn , i.e. Kronecker delta with first index of F_pq and first index of F_mn, and second Kronecker delta for second pair of indices q & n.

However the problem arises when we have a product of two or more tensors. Is the following (using chain rule) a valid derivative?

Overview of solid mechanics

kinematics. constitutive relations

This video (LINK) attempts to give the big picture of solid mechanics along with the brief explanation of the constituent topics.

This is an educational outreach initiative targeted at all engineers interested in mechanics and seek simpler explanations. Kindly share if you learn something out of this !

Thanks,

Postdoctoral position at the Technion - Israel Institute of Technology: A multiphysics modeling of electroactive polymers

Submitted by Mahmood Jabareen on Sat, 10/07/2017 - 22:28

job

Due to their large deformation capability, electroactive polymers are promising materials for several engineering applications. They can be used, for example, as actuators and sensors in artificial muscles, biomedical devices, microrobots, pumps, valves, etc. The research in this emerging field focuses in the multiphysics modeling of electroactive polymers and combines many aspects of structural mechanics, composite materials (for modeling composite electroactive polymers), and failure mechanisms of structural components and materials.

Metallic and highly conducting two-dimensional atomic arrays of sulfur enabled by molybdenum disulfide nanotemplate

Element sulfur in nature is an insulating solid. While it has been tested that one-dimensional sulfur chain is metallic and conducting, the investigation on two-dimensional sulfur remains elusive. We report that molybdenum disulfide layers are able to serve as the nanotemplate to facilitate the formation of two-dimensional sulfur.
