Constitutive models for granular materials including quasi-static frictional behaviour: Toward a thermodynamic theory of plasticity

Continuum Mechanics and Thermodynamics, 1999
This work is devoted to the generalizations of Mohr-Coulomb approach to the modeling of granular materials, based on hypoelastic and hypoplastic theories. The formulations and analyses of such models are given from a phenomenological-thermodynamic point of view, in the context of Müller-Liu entropy principle.

Modelling the thermodynamic growth of sea ice: insights from quasi-static models

2023
The thermodynamic growth of sea ice is governed by heat transfer through the ice together with appropriate boundary conditions at the interfaces with the atmosphere and ocean. Several different representations of this process have been used in climate modelling, including the simplest zero-layer models (Semtner, 1976) and more complex partial ...

Self-adaptive molecule/cluster statistical thermodynamics method for quasi-static deformation at finite temperature

Acta Mechanica Solida Sinica, 2011
Hybrid molecule/cluster statistical thermodynamics (HMCST) method is an efficient tool to simulate nano-scale systems under quasi-static loading at finite temperature. In this paper, a self-adaptive algorithm is developed for this method. Explicit refinement criterion based on the gradient of slip shear deformation and a switching criterion based on ...

Thermodynamics of an Irreversible Quasi-Static Process

American Journal of Physics, 1960
Quasi-static processes are not reversible when sliding friction forces are present. An example is considered consisting of a cylinder containing a gas and equipped with a piston for which sliding friction forces are significant. It is assumed that the frictional force may be a function of temperature, displacement, and direction of motion.

Thermodynamic Modeling of Granular Continua Exhibiting Quasi-Static Frictional Behaviour with Abrasion

2002
The deformation of a granular heap under the presence of external forces may be described by constitutive relations known as hypoplastic material equations. They describe internal frictional behaviour but ignore abrasion due to interparticle rubbing which is reported to be partly responsible for the formation of localized shear bands and associated ...
