Finite-speed heat propagation as a consequence of microstructural changes

PM Mariano - Continuum Mechanics and Thermodynamics, 2017 - Springer
We show how a general description of microstructural changes in a macroscopically rigid
conductor implies finite-speed propagation of temperature variations. In this way, we …

A continuum damage–breakage faulting model and solid-granular transitions

V Lyakhovsky, Y Ben-Zion - Pure and Applied Geophysics, 2014 - Springer
We present a thermodynamically-based formulation for mechanical modeling of faulting
processes in the seismogenic brittle crust using a continuum damage–breakage rheology …

Dynamic rupture and seismic radiation in a damage–breakage rheology model

I Kurzon, V Lyakhovsky, Y Ben-Zion - Pure and Applied Geophysics, 2019 - Springer
We present simulations of dynamic ruptures in a continuum damage–breakage rheological
model and waves radiated by the ruptures and observed in the far field. The propagating …

Continua with partially constrained microstructure

P Giovine - Continuum Mechanics and Thermodynamics, 2022 - Springer
The mechanical balance equations for a body with microstructure are derived from an
expansion of the general Noll's axiom of frame-indifference that takes into account the …

Multi-scale kinetic description of granular clusters: invariance, balance, and temperature

G Capriz, PM Mariano - Continuum Mechanics and Thermodynamics, 2018 - Springer
We discuss a multi-scale continuum representation of bodies made of several mass particles
flowing independently each other. From an invariance procedure and a nonstandard …

[HTML][HTML] Internal constraints in the theories of immiscible mixtures for soils

P Giovine - International Journal of Solids and Structures, 2020 - Elsevier
In this paper we formulate balance principles for an immiscible mixture of continua with
microstructure in the broadest sense to include, eg, diffusion and adsorption phenomena …

An extended continuum theory for granular media

P Giovine - Mathematical models of granular matter, 2008 - Springer
In a dilatant granular material with rotating grains the kinetic energy in addition to the usual
translational one consists of three terms owing to the microstructural motion; in particular, it …

Notes on constitutive relations for porous solids

P Giovine - Views on microstructures in granular materials, 2020 - Springer
The thermo-mechanical balance and constitutive equations for a porous material with large
irregular pores are investigated by imposing internal kinematic and thermal constraints on …
