| Abstract: |
This paper presents a methodology called ‘GUSTL’ [1], which is designed to efficiently estimate the parameters of a Prony-series representation of linear-viscoelastic material behaviour using measured data of the complex modulus 𝑬∗(𝑓) obtained in a dynamic mechanical thermal analysis. ‘GUSTL’ is based on the idea of solving an inverse problem, established as a physically motivated system of linear equations, by a nonnegative least-squares procedure. The whole methodology is validated against sample data from an epoxy-coated carbon reinforcement grid for concrete structures. |
