Within the



7th Research Framework Programme of the EU (FP7),

The project "Macro, Micro and Nano Aspects of Machining - MAMINA"

offers a three-year PhD project

named

"Finite Element Simulation of the Cutting Process"

at the Institut für Werkstoffe, Technische Universität Braunschweig.





Within the PhD-project Finite Element Simulation of the Cutting

Process (ESR 2) the cutting process will be simulated using finite

elements. Different models will be developed and the material

I have implemented a 2D co-rotational truss formulation in matlab.  I get identical results to OpenSEES.

Now I'm trying to implement a 2D co-rotational beam formulation.  I have followed the simple formulation in Crisfield's book volume 1.  It seems like this should be a fairly straight forward extension of the truss formulation.  I have rederived everything Crisfield has done and obtained the same results, yet something is still incorrect.

For a system in thermal contact with the rest of the world, we have described three quantities: entropy, energy, and temperature. We have also described the idea of a constraint internal to the system, and associated this constraint to an internal variable.

A recent paper on JMPS has seriously questioned the foundation of the SGP theory of Fleck and Hutchinson.  The matter is not simple, but is it a good bench test for imechanica to discuss?
