Published in 2021 at "Mathematical Methods in the Applied Sciences"

DOI: 10.1002/mma.7306

Abstract: An innovative numerical procedure for solving the viscoelastic arch problem based on variable fractional rheological models, directly in time domain, is proposed and investigated. First, the nonlinear integral‐differential governing equation is established according to the… read more here.
