Hello,

 

I am working on model having rubber seal. I want to find out deformation in seal when force applied on mating part. Which Material Model and analysis Type i should use in order to do analysis in case of rubber

 

Thanks in advance,

Hi Teja,

 

Can you please share the model file?

Hi Teja,

 

I ran the file which you shared without any modifications and I didn't see any error and the solver starts the calculations. 

 

Which version of HW are you using?

 

I used 2017.2

OK, this is because there is no stress strain data for any mat1/mats1 and MATHE doesn't provide plastic strain as output
