Converting viscoelastic Prony Series terms from ABAQUS to LS-DYNA
In Abaqus,
g(t) = 1 - ∑(gi * (1-exp(-t/taui));
in which g and gi are dimensionless.
In LS-DYNA,
G(t) = ∑( Gi * exp(-betai * t) );
in which G and Gi are in N/m2
Based on this information, how do we transform the Prony Series terms from one code to another or vice-versa given I don't have the test data available.
