Moisture absorption in adhesive

Submitted by mahzanjohar on Tue, 04/09/2013 - 05:47

Dear all,

Need Help..

I'm doing research in moisture absorption in adhesive bonding. I'm wondering how to differentiate and characterize the Fickian Diffusion and Non-Fickian Diffusion during absorption and desorption moisture.

Thank You

A single strand of polymer is a chain of a large number of monomers. The monomers are joined by covalent bonds, and two bonded monomers may rotate relative to each other. At a finite temperature, the polymer rapidly changes from one configuration to another. When the two ends of the polymer are pulled by a force, the distance between the two ends changes. The polymer is known as an entropic spring.

Hi, I am a new PhD student working on the vibration behavior of a thin polymer film. Specifically the film is an elastomer VHB 4910. The question that I have specifically is that initially the film is 500 microns thick. Upon the application of prestress, the film is stretched (clamped) and the film thickness decreases to 20 microns. Assuming that the thickness is uniform, how can I calculate the tension in the membrane?

Thanks for any suggestions that you can provide, and happy new year!

Look for free-code UMAT on polymer viscoplasticity model of M.C. Boyce

Submitted by Liu Jinxing on Wed, 08/10/2011 - 16:09

I just attended USNCCM11, and heard from a presentation that there should be free code for polymer viscoplasticity model from M.C. Boyce.Unfortunately, I googled from half an hour and dowloaded nothing this afternoon. Can anybody give more info ?

Thanks in advance !

multiscale simulation

Hi,

I am searching on multiscale simulation of polymer/metal ( mechanical propertices).

Cohesive zone model is used for this porpose.

Is there another models that can use for this issue and using MD data as input?

Best regards,

high strain rate in MD simulations

Submitted by Azadeh Sheidaei on Sat, 04/02/2011 - 02:37

Dear All,

Recently I have read some literatures on Molecular simulation of polymer. My interest is measurement of

mechanical properties of polymer through the uniaxial tensile test.

I have a question about relatively large time scales in MD simulations of polymer and how to interpret MD

stress-strain results for FE modeling. In particular, in the literature it is mentioned that strain rate of
