Hi All,

What is generally the correct procedure for adjusting your experimental data for curve-fitting into ANSYS? Should the Force-PercentElongation curve be converted to TrueStress-TrueStrain...

Hi All,

I'm having a bit of trouble trying to develop a viscoelastic material model to couple with my hyperelastic model. I already have experimental stress-time curves for my material. I then...

Hi All,

I was wondering if the viscoelastic properties of vulcanized natural rubber are available somewhere. I intend to couple those properties with the basic stress-strain curves for simulation...

Hi Jorgen,

I was able to curve-fit by unchecking the "Use Normalized Error" checkbox in the curve-ftting dialog in ANSYS. I'm not exactly sure what purpose it serves, but the fits are good now.
...

Hi All,

I am trying to use my experimental data for vulcanized natural rubber for some finite element simulation in ANSYS, and noticed that the closest fit is given by Mooney-Rivlin. But...

Hi All. I intend to determine the softening temperature of carbon black loaded fully vulcanized natural rubber. I need to determine this in order to heat the rubber foam to change its structural...

Thanks for your reply Jorgen. The only thing I am confused about is whether fully vulcanized rubber/foam can be used in the rheometer or not. The standards I have seen so far only cater for the study...

Hi All,

I am not sure if this is the right forum to post this thread. If I have posted it in the wrong forum kindly move it to the most relevant one.

I intend to characterize the viscoelastic...

Hi Jorgen,

Many thanks for your reply. Yes my application would be purely compressive (impact), but I am still a bit skeptical about tri-axial compression testing. Wouldn't uni-axial compression...

Hi,

I intend to simulate the mechanical and viscoelastic behavior of a polyurethane foam which would be subject to impact and vibrational loads. I would like to know what tests I would need to...
