Development Of A Pavement Rutting Model Using Shakedown Theory
Autor: M. Boulbibane, I. F. Collins
Publikováno v: International Journal on Pavement Engineering & Asphalt Technology. 16:55-65
The rutting of flexible pavements during their exploitation is considered to be one of the main problems in UK as well as worldwide. It is a serious mode of distress alongside fatigue in bituminous pavements that may lead to premature failure, as ind

Thermomechanical state parameter models for sands
Autor: B. Qu, B. Muhunthan, I. F. Collins
Publikováno v: Géotechnique. 60:611-622
The granular structure of sands and other geomaterials makes them amongst the most difficult engineering materials to model. In this paper a recently developed thermomechanical procedure is used to derive constitutive models for sands undergoing tria

Constrained, thermomechanical, rigid-plastic models of granular materials
Autor: Piaras Kelly, I. F. Collins
Publikováno v: International Journal of Engineering Science. 47:1163-1169
Non-associated flow rules used to describe the plastic behaviour of geomaterials are normally expressed in terms of a plastic potential. It is shown that this is an overly restrictive assumption, and in general two such potentials are needed. In addi

A thermomechanical framework of plasticity based on probabilistic micromechanics
Autor: I. F. Collins, Itai Einav
Publikováno v: Journal of Mechanics of Materials and Structures. 3:867-892
A conventional thermomechanical elasto-plastic constitutive modelling framework is proposed but which allows an effective physical interpretation of the micromechanical internal variables and inherent parameters in a representative volume element (RV

The concept of a ‘Reynolds–Taylor state’ and the mechanics of sands
Autor: A. T. T. Tai, Michael Pender, B. Muhunthan, I. F. Collins
Publikováno v: Géotechnique. 57:437-447
A novel conceptual model of the mechanics of sands is developed within a thermomechanical framework. Central to this model is the realisation that volume changes in granular materials are induced by two mechanisms. One is purely kinematic, and is a r

The concept of stored plastic work or frozen elastic energy in soil mechanics
Autor: I. F. Collins
Publikováno v: Géotechnique. 55:373-382
This paper is part of a series that aims to explore systematically the applications of the modern theory of thermomechanics to the constitutive modelling of soils and other geomaterials. Although the division of the applied work into recoverable elas
