high strain rate
can anyone tell me how to perform high strain rate simulation in abaqus.
Many prior posts asked about manufacturers of Split Hopkinson Pressure Bar equipment. REL Inc in Calumet MI (http://www.relinc.net/products/hopkinson-bar/) designs, builds & installs custom equipment to meet your requirements. We offer a university discount. And, we provide in-house testing; manufacturing of samples, etc. A new offering in this field is our SurePulse software which simplifies the data acquisition effort for Hopkinson bar testing.
A question for the audience:
There is no ISO or ASTM specification for compression testing on Split Hopkinson Pressure Bar. We wonder if there is the need for such a standard? What do you think?

PhD positions available at Polytechnique Montréal and McGill universities on shot peening with 5 aerospace companiesSubmitted by martin.levesque on Mon, 2013-02-18 03:35.
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
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).
