Hi all

I am currently investigating Prager hardening room which is stated as the simplist linear kinematic hardening rule. I was wondering if anyone has worked with this model and if so if you have managed to identify how to determine the constant used for the back stress equation

dα =C * dε^p ( this is epsilon dot p which is the equivalent plastic strain)

Please can you let me know how to determine the constant C from experimental results? 

A postdoc position is available in the Theoretical & Applied Mechanics Group (http://tamg.mem.drexel.edu/). Of particular interest are expertise in subcontinuum and continuum computational mechanics methods. Available researh projects include both alloy and composite material systems. 

Applicants should submit a full CV, a statement of research and their earliest employment availability to akontsos [at] coe.drexel.edu.

Meeting of the working group Microstructural Mechanics of the DGM

Journal of Applied Mechanics (JAM) received 526 submitted manuscripts in 2013.  Among them 4 are still in review.  

The average time for the 1st round of review, with the decision to accept, or reject, or revise, is 18 days.  After the 1st round of review, the average time to make the final decision is 34 days, which include both the authors' revision time and 2nd (and more) round(s) of review.

After acceptane the uneditted manuscript appears online with the assigned DOI within 48 hours.

We are seeking a highly qualified candidate for a full-time postdoctoral researcher position in the area of Computational Mechanics at the Graduate Institute of Ferrous Technology (GIFT), Pohang University of Science and Technology (POSTECH), Korea. Candidates with a strong background in continuum/dislocation-based plasticity theory, computational mechanics of sheet metals, FE modelling of sheet metal forming processes… are highly encouraged to apply.

Abstacrt: A multi-phase field model was developed for non-selective oxidation of metals which captures both the oxidation kinetics and stress generation. Phase field formulation involved a non-conserved phase field variable as the marker for the metallic substrate, oxide scale, and a fluid phase containing oxygen, and a conserved phase field variable representing the concentration of oxygen.

i have presented a new method for the first time to model of metal foams that subtracts stochastic cells from a desired volume and changes it to a foam.

i would like to know if there is any phd position for this?

thank u for your consideration :)
