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

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...
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,

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

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!
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.

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

Hi everybody,
I am working on contact problem between rubbers, I have difficulties to observe the contact (only some microns width and over the length more than 30cm). Does anybody know methods to measure contact of difficult accessible part? I mean like a moulding method??
thanks for your...
hello
New user of Abaqus, i am working on rubbers contacts, and would like to use Abaqus to understand contact pressure, crack propagation, and make wear prediction.
WOuld you give me some tips?
Thanks
