Determining a Prony Series for a Viscoelastic Material ...

each Prony series term is associated with a material internal state variable. In the discrete finite element model, each term in the Prony series adds a substantial number of global variables. Thus, a short Prony series, which can accurately represent the material, is desirable. Nonlinear regression methods can help with determining a short and ...
