Effective Rheology of Bi-viscous Non-newtonian Fluids in Porous Media
Frontiers in Physics, 2020 We model the flow of bi-viscous non-Newtonian fluids in porous media by a square lattice where the links obey a piece-wise linear constitutive equation.

Compressive deformation behavior modeling of AZ31 magnesium alloy at elevated temperature considering the strain effect [PDF]
Materials Research, 2013 The true stress-strain data from isothermal hot compression tests, in the temperature range of 300-500 ºC and strain rate of 0.001-0.1s-1, were employed to study the flow behavior of AZ31 and to develop constitutive equation based on an Arrhenius-type ...

On a Generalized Wave Equation with Fractional Dissipation in Non-Local Elasticity
Mathematics, 2023 We analyze wave equation for spatially one-dimensional continuum with constitutive equation of non-local type. The deformation is described by a specially selected strain measure with general fractional derivative of the Riesz type.
