Viscoelastic properties of pre- and post-cure cellular rubbers using rheometer

Submitted by farhan3d on Tue, 11/22/2011 - 12:35

Hi All,

I would like to know if anyone has had the opportunity to investigate cellular rubbers rheology. I am thinking of characterizing the viscoelastic properties of cellular rubber during cure and after cure in the rheometer, using ASTM D6601. What I am expecting is a distorted cellular structure due to very constrained foam expansion during the blowing agent's decomposition, so the results would obviously be different than the ones obtained from a DMTA machine.

Would like to hear from anyone with some rheology / viscoelastic characterization experience.

Is it possible to otain the time history from the response spectrum?

Thanks in advance

Hi everyone,

Will really appreciate if you can refer me to some literatures that works on vibrational characteristics of single-walled carbon nanotubes using nonlocal elasticity.

Hi All,

Can you please suggest me some good books or online links to understand the theory/applications of Molecular modelling. I am in Mechanical Engg. Dept. and new to this subject. Currently I have started reading the book by Andrew R. Leach (Molecular Modelling principles and applications)

Hello

non linear frequency analysis

Submitted by phrankie81 on Thu, 11/17/2011 - 16:36

research

Hi,

I'm trying to run a frequency analysis of a composite beam with non-linear properties in Abaqus. Is it possible to make use of the non-linear properties in the frequency analysis. If so how can I do it?

Composite beam in this case refers to a combination of steel and concrete.

Any detailed contributions will be appreciated.

Thanks
