Hello,
This is my first post on the website so I apologise if I make any mistakes.I am doing a riveting analysis in ABAQUS/standard. It has two aluminum plates joined together by an standard aluminum rivet. It involves large deformations and plasticity.
Now, I want to introduce a sealant in between the two plates. I want to model the sealant as an elastomeric material using hyperelastic material. Since the rivet will compress the plates I want compressive stress strain data. I dont have that but I had gone through the abaqus examples problems and they have constants (Mooney rivlin etc.) fitted for rubber gaskets etc. I was thinking of using those.
Also, this website also has lot of data for uniaxial compression for different rubber materials. The data is given for different strain rates. If I use that data do I input a sepcific strain rate data in abaqus? or do I have to input data at all three strain rates? Is the data suitable for my analysis?
Since purpose of sealant is to seal the plates do I use regular contact in abaqus or do I use Tie constraints for adhseive and plates?
Any suggestions, help will be greatly appreciated. Thanking you ina dvance.
