Abstract: Abstract Elasto-viscoplastic fluid flow in tubes of arbitrary cross-section is explored. A constitutive equation superposing elasticity on the viscoplastic behavior through a linear combination of the non-linear simplified Phan–Thien–Tanner constitutive model of viscoelasticity and the… read more here.

DOI: 10.1016/j.jmps.2020.103874
Abstract: Abstract To model the mechanical response of rate-dependent elasto-viscoplastic (or equivalently nonlinear viscoelastic) particulate composites, the proposed approach consists in linearizing the (nonlinear) relation between the viscous strain rate and the stress. To obtain a… read more here.
