Hi there,
I think the source you attached is plainly badly written. They clearly state Table 2 should contain the fitted values for the cases plotte...
Dear Martin, in reference to your points: 1. any deformation on elastic materials can be decomposed in volumetric (volume changing) and distorsional ...
Hi there,
I would like to throw my thoughts in. Your problem is quite complex. When compressed above a certain threshold, rubber in compression can p...
Dear Tarup, in reference to your first point about linear viscoelasticity, there are very easy ways to check if linear viscoelasticity can be applied...
Hello David, I do hope I am not being rude or generally inappropriate, may I suggest a very useful reference, Viscoelastic solids by Prof. R. Lakes....
Mr. Inventor, I am really unsure that would work. The equation you point at is not objective, i.e. frame independent. One could look at a state of sh...
I see your problem now, one I am quite familiar with! Back to your problem, I am not so sure I understand your plan. If you compare principal stretch...
Feihuzhao, thanks for the reply. Let me explain better my question. Lets assume my material has a relaxation time of 1000 sec, and I need to compute...
Hi FEGuru, and thank you for your suggestions. Just for clarity, are you implying I should switch to some viscoplastic model? (you mention permanent...
Jorgen, many thanks for your advice. I am not conversant at all with USERMAT subroutines in ANSYS and, even if a 1 - D model was available, I would ...
Manfred, many thanks for all this, I appreciate it must have taken you some time. I understand what you say about the suitability of the two methods...
Manfred, thank you for your post and the attachment. I understand what you say. We have already performed a forecast using an Arrhenius based tecniq...
