Viscoelastic properties of pre- and post-cure cellular rubbers using rheometer
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.
seismic analysis
Hi
Is it possible to otain the time history from the response spectrum?
Thanks in advance

T-stress
can any one suggest, how to apply T-stress in modified boundary layer (MBL) analysis.
Nonlinear Dynamic Structure
Iam a Ph D student and I am searching for a tutorial or a book which looks into nonlinear vibration analysis of beams or dynamic large dispacement analysis of beams using ADINA method. I hope anyone can help me send me for the email: othmanomr [at] yahoo.com (othmanomr[at]yahoo[dot]com)
Question about "usage of atmospheric flares (burners)" in refineries
Why do we use "atmospheric flares (Burners)" in preheat gas furnaces of refineries? What are benefits of usage of these kind of flares (burners) in refineries, in comparison whit other flares?!!!
Elimination of Rigid Body Motion
Hello everybody
I'm doing some experimental research by the help of DIC method, But I have a huge problem that I hope someone can help me about that. After capturing my datas, I realized that there is a constant value of rigid body motion that is added to my real datas and so that all of my results seem to be wrong. I was wondering if anyone knows how to eliminate this rigid body motion ( translation or rotation) from my datas.
Thanks in Advance
Finding a node by using the coordinates
I am failry new to Abaqus. I am working on Abaqus CAE. I want to find the nodal temperature ouput for a particular location.
I know the location(X;Y;Z) values but i dont know the node label. How to do i identify the node in CAE?
