Re: Rubber Block
What version and sp?
Have you spoken to your reseller about this?
Just to confirm, with a linear material the problem solves without issue?
What material model for nonlinear do you want to use?
In the long run, what are you trying to learn from the study?

Re: Rubber Block
- Its a 2012-2013 SP5.0 I believe
- I have not spoke to the reseller no; I am with a university, trying to conduct research
- Yes it solved with linear material, say picking steel
- The model I would like to use is non-linear elastic, the material I am trying to model is under compression, the other methods seem like are for tensional purposes
- Learn how rubber behaves under an impact load. Specifically its Strain-rate dependecy

Re: Rubber Block
Learn how rubber behaves under an impact load. Specifically its Strain-rate dependecy < in this case, are you sure that nonlinear elastic is the best choice?

Re: Rubber Block
Hi Jared,
I am not sure it is the best choice. I am trialing each one to see which gives the best result to match the experimental data.
But I am unable to work any of the models. I am not sure if the raw data I am obtaining matches what SolidWorks require

Re: Rubber Block
where are you getting the data from? what is the raw data that you are entering. not necessarily just the numbers but is it engineering stress/strain, is it stretch ratio..etc.
if you care specifically about the strain-rate dependency, i'd recommend going through the material models in the help. i think you're going to see that there are very few that will support that need. and from there it will tell you what you need from an input perspective.

Re: Rubber Block
Data is from an Instron Compression Tester. Compressing a rubber sample.
the .dat file is in the format of:
First Column: Strain Second Column: Stress
I will have a look at the materials model. Thanks

Re: Rubber Block
so most likely true stress and strain. some materials require eng stress and strain as outlined in the help.
