Experimentally informed multi-scale modelling of mechanical properties of quasi-brittle nuclear graphite

Submitted by shavijabranko on

Dear all,

Our group has just published a paper on experimentally-informed multi-scalle modelling of nuclear graphite in the journal of Engineering Fracture Mechanics. It can be of interest to anyone working on quasi-brittle fracture and materials such as graphite, concrete, rock, shale, or similar. It can be downloaded at:http://www.sciencedirect.com/science/article/pii/S0013794415007080

Regards,

Branko

Postdoctoral Associate Position at the Department of Petroleum Engineering, Texas A&M University

Submitted by sabedi on

A postdoctoral associate position is available at Department of Petorleum Engineering, Texas A&M University in the area of resistivity characterization of geomaterials. Experimental characterization at nano-scale will be combined with modeling techniques to get insight into electrical properties of geomaterials at fundamental length scales. Expected qualifications:A Ph.D. in materials science, civil engineering, geophysics or a related field is required.

Multiple Postdoctoral/Research Engineer Positions at Masdar Institute in collaboration with MIT

Submitted by upriyank on

Advanced Materials and 3D Printing Lab at Masdar Institute invites applications for Project-Postdoctoral Positions to work on a multi-disciplinary collaborative project funded by GASCO (ADNOC), Abu Dhabi.  Successful candidate(s) will work in the Institute Center for Energy (iEnergy) and will be based in Mechanical and Materials Engineering (MME) department at Masdar Institute. These positions warrant regular communication with the international collaborative team (MIT, TAMU and Lockheed Martin). 

Aneurysm rupture

Submitted by Konstantin Volokh on

Aneurysms are local dilations of the arterial wall that are prone to rupture with high mortality risks. The biochemical mechanism of the aneurysm development is not clear. The mechanical mechanism of the aneurysm rupture is not clear either. I attach three papers that study two possible mechanisms of the aneurysm rupture.

Mesoscale Constitutive Modeling of Non-Crystallizing Filled Elastomer

Submitted by Ajay B Harish on

We have just published a new paper, 1st in the series, that presents a computational model to understand the microstructural changes in the filled elastomers as a consequence of mechanical forces. A heterogeneous (or multiphase) constitutive model at the mesoscale explicitly considering filler particle aggregates, elastomeric matrix and their mechanical interaction through an approximate interface layer is presented. An innovative lego-set method is discussed for generation of random microstructures that can be used for simple stochastic analysis.

Extreme Multiscale Modeling - 53.8 Billion finite elements

Submitted by karelmatous on

In our recent Extreme Mechanics Letter, we present a simulation consisting of 53.8 Billion finite elements with 28.1 Billion nonlinear equations that is solved on 393,216 computing cores (786,432 threads). The excellent parallel performance of the computational homogenization solver is demonstrated by a strong scaling test from 4,096 to 262,144 cores.
