recommendations! Published in 2017 at "Mechanics of Time-Dependent Materials"

DOI: 10.1007/s11043-016-9335-7

Abstract: Asphalt binder is responsible for the thermo-viscoelastic mechanical behavior of asphalt concrete. Upon application of pure compressive stress to an asphalt concrete specimen, the stress is transferred by mechanisms such as aggregate interlock and the… read more here.

DOI: 10.1007/s11043-020-09473-x

Abstract: Polymers exhibit viscoelastic behavior: their mechanical response depends on the loading time, or on the loading frequency. In addition, if a polymer structure has a long service life, the mechanical behavior can also depend on… read more here.

DOI: 10.1016/j.apm.2017.06.018

Abstract: Abstract This paper aims to present a viscoelastic constitutive model of rubber-like materials, which can capture the Payne effect under dynamic cyclic loadings. The Payne effect is induced by a damage process of bond rupture… read more here.

DOI: 10.1016/j.finel.2018.04.003

Abstract: Abstract The aim of this paper is to present the implementation of 3D fractional viscoelastic constitutive theory presented in Alotta et al., 2016 [1]. Fractional viscoelastic models exactly reproduce the time dependent behaviour of real… read more here.

DOI: 10.1016/j.ijsolstr.2020.04.011

Abstract: Abstract In this paper, a novel nonlinear viscoelastic constitutive model is proposed to describe the mechanical behavior of a polymer matrix composite (HTPB propellant). The model is built upon two stress-dependent nonlinear functions within the… read more here.

DOI: 10.1016/j.jnnfm.2017.04.005

Abstract: Abstract A viscoelastic constitutive model which combines the partially extending strand convection model and a Newtonian solvent is used in the regime of large relaxation time. Prior work on one dimensional time-dependent solutions at prescribed… read more here.
