I'd like to analyze rubber like O-ring (NBR) with non-linear quasi static.

I try to define this as MATHE MONEY model.

Which parameter should be inputted ? NU, RHO, TEXP, C10, C01 ・・・

I want to know common parameter like NBR.

    Hi,

     

    What parameters do you have?

     

    You need C01, C10, Nu, RHO, I and J invariants will be calculated by OptiStruct, Internally!

    thank you,

    I input for the moment,

    NU 0.495, RHO 0.0001 from OS-E- 0185,

    C01=80, C10=20, D1=0.001 from example from https://connect.altair.com/CP/kb-view.html?kb=166646

    Does this parameter indicate rubber like NBR?

    Where should I read to obtain these parameter?

    Hi @naoki

     

    If you need NBR like parameters, I would suggest you refer some past papers or contact suppliers. They can provide material data for NBR with different hardness.
