Inhomogeneous creep equation for viscoelastic materials

Abstract

The paper consider an inhomogeneous creep equation arising from a generalized Voigt model containing a Riemann-Liouville fractional derivative of the order 0 < β < 1. The Laplace transform is used for the numerical solution. The obtained solutions are compared with experimental data of polymer concrete samples. On the basis of this comparison the conclusion about the adequacy of the numerical solution method is made, and estimates of the model parameters are given.
