A Constitutive Model for the Sintering of Fine Grained Aluminan be divided into two groups, namely micromechanical and empirical models. Micromechanical constitutive laws have been developed from simple models of the way in which the microstructure evolves during the compaction process. These models provide detailed forms of relationships which can then be com

The Use of Legendre Transformations in Developing the Constitutive Laws of Geomechanics from Thermodoks by Ziegler (1983), Lemaitre and Chaboche (1990) and Maugin (1992), and the articles by Germain, Nguyen and Suquet (1983) and Ziegler and Wehrli (1987) provide general accounts of these developments. Whilst these approaches provide a very elegant unified development of the theory of many of the m

Derivation of Incremental Stress-Strain Response for Plasticity Models Based on Thermodynamic Functiof a yield surface in stress space, enclosing a region in which the strains are substantially elastic, is well established empirically. The validity of the concepts of a flow rule and hardening law are also well established for many granular materials. Within this broad framework many constitutive m

Three-Dimensional Discrete Mechanics of Granular Materials particles, the discrete-mechanical formulation is considered to be natural and fundamental, and such approaches have been proposed by using graph theory [1–4]. Although the approach was two-dimensional and limited to the case of circular discs in the preliminary studies, the extension to the case o
