I am using Abaqus (with CAE) and not sure if I can specify tension and compression modulus together.

Thanks for the reply.Unfortunately the material has significant plasticity involved and hence I cant model using hyperelastic laws.

Hi I have a general question on whether to use Compression or tension test data for plastics in FEA modeling? I have come across couple of PTFE based plastics where compression modulus is twice as much the tension modulus. For metals I observed it would be nearly the same so doesnt matter which...

Thank you everyone for your suggestions. This is how I understood calculating the formula. (Please look at the attached picture). Please let me know if my understanding does not make sense. Thanks FM...

Hello This may be simple but I am unable to calculate this. I have a band clamp pressing a rubber seal tight. I have the torque applied on the band clamp as 5 N-m. How can I convert this torque value into a radial contact pressure acting on the seal surface? I have all the specifications of the...

Thanks for the reply. Have attached the input file.http://files.engineering.com/getfile.aspx?folder=1c65d5bb-d12a-4fd8-9d7b-c0719e7a974d&file=9729-Lipseal-2D-Hflux-for-temp-Rigid.inp

I forgot to mention that I am assuming 30% of the calculated heat flux will go into the slave surface.

Hi I am trying to predict heat generated by friction in rotary seals using Abaqus. I have already completed the analysis however I am not sure whether I did it correctly. I have modeled coupled-temperature displacement steps for the analysis.In the first step I have the assembly of the seal...

Hi There are messages of overclosures in the model. Either you should move the top rigid body up so that it doesnt interefere with spring surface initially and then push it down the distance you need or activate shrink fit in your rigid top vs spring surface contact by going to interefernce fit...
