Im designing a protection cap for a connector using DuPont Hytrel thermoplastic elastomer. The interference fit between the cap and the connector plastic (Zenite) housing provides the retention force.
Which hyperelasticity model to be used for the cap material?
Is there any concern on the stress relaxation due to the interference fit on the cap?
Please see the attached picture of the concept (cross-section view) and the material data.
It seems that I only have the tensile stress-strain data and Im not sure if thats sufficient for any hyperelasticity model in ANSYS
Thanks in advance for any help/advice.
