Ok, good, I will have a look. The interesting thing, what I have recently discovered, is that it is better to use as less possible friction coefficient between acting part of the press (facets) and specimen (better 0). So, we imitate greased by oil the surface of the press.
In this case we get the most stable results. If the friction coefficient is large (for example, 0.4-0.5), results are changing randomly, depending on size specimen, number of grains etc... What do you think about that? 2010/4/30 Václav Šmilauer <[email protected]> > > > I do not think, it will be seriously different from the uniaxial > > strainer, which you use now. > > > > The most important feature of PressTestEngine, it defines whether the > > specimen destructed, then rises up the acting part of press and stops > > the simulation. > > I need it for "automatic" tests, when I do not know an exact number of > > steps. > Watch out what boundary condition you need boundary conditions, though > (friction with facets etc).
