This MATLAB code is used to determine the parameters of an extended Maxwell model (Prony equation). It optimizes the Prony parameters n, gi and ki considering the best fit for the curves of G´(ω), G´´(ω) and tan delta (ω) using the function lsqnonlin from MATLAB Optimization Toolbox. An Excel-File is needed for input with values from DMA measurement acc. DIN EN ISO 178 (Table of frequency / storage modulus / loss-modulus) and from tensile test acc. DIN EN ISO 527-1 (modulus of elasticity and Poisson’s ratio).

Please find further details (Introduction, Physical Background, MATLAB code, Acknowledgements, Reference List) in attached PDF-manual.
