If you are interested in elastomers and electric vehicles, check out this link to RIEG webinar on Elastomer use in Electric Vehicles. There were 4 talks covering elastomer requirements for EVs, mounting system design for EVs, use of carbon black in EV applications, and EV mount integrity digital twin. Enjoy!

Hello,
I am doing a project on rubber couplings and it is a bit difficult for me to decide between the material models availavle in Ansys 14. I am new to this field and want some assistance in choosing the material model. So, can anyone help me to theoroticall explain the difference between the different material models available in Ansys?
In the notes on the general theory of finite deformation, we have left the free energy function unspecified. The notes here describe free energy function commonly used to describe the elasticity of rubber-like materials. These notes are part of a course on advanced elasticity
Hi.
I found a very useful explanation about hyperelasticity here: http://en.wikipedia.org/wiki/Hyperelastic_material#cite_note-Ogden-1
In the proof3, there is a good explanation (I can't found anything better than this one) of how we can express the Cauchy stresses in terms of the principal streches.
I am interested to incompressible material, so this is the equation:

Hi,
I know what is this test and I know under certain conditions (low deformations and specimen's wide 10 times its lenght), a planar tension test is equal to pure shear test.
But I don't know why if we are doing a tension test we have pure shear.
Let me explain:
Natural rubber (NR) is known to crystallize under strain (SIC) so that NR samples subjected to loading-unloading cycles exhibit hysteresis. A brief review of the numerous experiments conducted on this material is given. Detailed information on the microstructure is therefore available, particularly simultaneous measurements of stress versus elongation and

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.
