hi all i am doing Masters my project is Elastomer gasket life prediction using Fea.
my project objective is predict the service life of elastomer gasket in intake manifold of engine.
i am using the tool abaqus.its an visco hyperelastic approach. constitutive model consists of
hyperelastic: Ogden model
viscoelstic :prony series
in order to curve fit in prony series. i didnt know how? inabaqus option is only for volumetric and shear test data. i didnt know how many hours i have to do stress relaxation test to fit in prony curve?
any body help me
