Hello everyone,

there is unfortunately no category for Thermoplastic Elastomers, but I hope my topic is placed well here.

I want to use a FE-Model to describe to compressive behaviour of TPE seals. As I am totally new to that topic I have some basic questions.

1) I am using Altair HyperWorks (including a user material interface). Does anyone have experience with a built-in model or a user-model?

2) Can you recommend testing routines (according to norms) that can capture the compressive material response well?

3) Are there important details that I have to be clear of when modeling TPE?

Thank you so much in advance for any information!

Best regards

Jo

1. I have limited experience with HyperWorks 🙁

2. I have tested and simulated MANY different types of TPE materials. Suitable experimental techniques are described in my [URL= http://polymermechanics.com/ ]book[/URL] and also on this [URL= https://polymerfem.com/content.php?11-Experimental-Data ]page[/URL].

3. TPE material are typically very non-linear. I recommend that you work hard on the experimental and material calibration steps.
