my project is life prediction of elastomer gaskets in ic engines using fea. how can i select the constitutive model and the life prediction associated with which mechanism whther stress relaxation, stress softening or excessive creep

I m Manoj, doing my Mtech in CAD/CAM. I m doing my project work in design analysis & optimization of seatback of car seat. I want the information about rear impact & theory material for the same.
Thank's all in advance.
I think the concepts from the constitutive theory, but in many papers the researchers seem that they dont differentiate them. So could you give me an exact explanation about it? Thank you.

Can anyone plz send me instructions on how to calculate the coefficients a,b,c,d,h (f,g = 1) for YLD91 and subsequent ones? I have a rough idea, but if someone has explicit instructions ..
In the finite element simulaiton of material failure, the simulaiton results are critically dependent on the element size if the mateiral is described by a softening constitutive relationship. How to resolve this problem? What is the underlying principle of this phenomenon? Thanks!
For fatigue life estimation (HCF & LCF), I am not sure which stress shall I consider i.e. max. principal stress or von Mises stress & what should be the criteria for selection of the same? Shall we be driven by material model (i.e. ductile or brittle) or mode of failure or some thing else?
