Ecole Polytechnique and McGill are seeking two PhD candidates for a large project aiming at understanding the effects of shot peening on the fatigue lives of aerospace components. The project involves 8 PhD students that will be working in close collaboration. The project is co-funded by the Canadian goverment and 5 leading aerospace companies located in Montréal. Some projects involve internships at these companies.

We are seeking two students for the following projects:

Shot peening for fatigue life improvement

The Department of Engineering Science at Oxford University has recently obtained funding for a project to develop novel experimental techniques for characterising and modelling the response of rubber-like materials to impact loading.  The project will support two studentships, supervised by Dr Clive Siviour in the Solid Mechanics and Materials Engineering Group.

Dear All, 

Recently I have read some literatures on Molecular simulation of polymer. My interest is measurement of

mechanical properties of polymer through the uniaxial tensile test.    

I have a question about relatively large time scales in MD simulations of polymer and how to interpret MD

stress-strain results for FE modeling. In particular, in the literature it is mentioned that strain rate of

I have attached a copy of my McMat07 talk below.  The talk is about a modified mechanical threshold stress (Follansbee-Kocks) model that can be used for strain rates > 1000 /s and high homologous temperatures.  In the model, the pressure dependence of the flow stress arises from the pressure dependence of the shear modulus.  Even after using the most accurate models for the shear modulus (and the melting temperature) we find that the pressure sensitivity of the flow stress is underestimated by our model (by quite a bit).
