Hello everybody, My question concerns contact roughness measurement. I have a talysurf in my laboratory. I would like to measure roughness on the polycarbonatre surface. It's destrying the surface, and I would like know if it is possible to estimate the wear induced by the talysurf to...

Hello everybody, I am trying to look at the FFT of a sound signal. I used for it scilab. The problem I have is that there is a lot of noise, and I do not know how to remove it. What kind of filter should I use? Please answer simply, I am not used to signal treatment analyzis! thank you mereaux

Thank you for your advice! The last weeks I tried to encourage more people to have interest in what I am doing. I get more contacts like this and it make me life better. I go every time to people who know the process. It is not really a team, but I think with perseverance I can get one... At...

Hi everybody, I work since 7 months and I am doing research on a very interesting subject to me. Most of the time I am working alone (I do research in a production place, where mostly people are product/process engineers). It is my first experience, I am in a foreign country, I am not real...

Hello everybody, One of my projects conducts me to the use of lead screw, to travel an object above a surface. This device is quite small, as small as the laser device of a CD player. I wanted to use the travelling system of a CD/DVD player, however I do not get the information I need. I am...

OWG, Thank you very much for your quick answer! What do you mean by correlation? Do you know such correlation available for all solvent? Could you explain me it? thank you. Mereaux

Hello Everybody, I am working on powder deposition with a solvent which evaporates. I have to change the actual solvent by another, which evaporates slower. I have datasheets of the two solvents, it is indicated the evaporation rate and also a reference BUOAC=1. I do not understand what it...

Hi everybody, I am working on a cartridge and I would like to make a simulation of the behavior of toner pushed by a rubber bar on a turning cylinder. Does anybody know software about it? Thank you very much in advance, Mereaux

Hi everybody! I would like to know if there is any relation between melt flow index and viscosity. I know when the MFI increases the viscosity decreases, but is there any precise relation between these 2 measurements? thanks Mereaux

Hi everybody I tried those films, but it is not precize enough in spite of the fact I hav emore information about the pressure between my rubbers. any other idea? Mereaux

Hello everybody, Could someone explain to me, what is the kinematic coupling in abaqus. I have read the user manual. But I do not understand what is the function of the reference point? Should this reference point have boundaries conditions? What happen then to the coupling nodes? thank you!

I am looking on contact surface, by simulation and experiments... contact between rubbers. I would like at least to make approximation by theoritical calculation, that is why I need such information on mechanical properties at a microscopic scale. And I don't know what are the theory on this...

Hi everybody! Do somebody know here any theory about mechanical properties of materials (plastic, rubbers) at a microscopic scale. Is there any apporximation? Thank a lot for answer. Mereaux

Hi JulianHardy, I would like to know if you are satisfied of this software now? Is it easy to use? What can this software simulate, I see the wwebsite but I dont understand ? Thank you for you answer!

hi! Do you know how we can measure the viscosity of powder? Does it exist a model to describe the viscosity of powder when it does not flow? thank you mereaux
