A thermo-mechanical constitutive model for fine-grained soils based on thermodynamics

The formulation of a new thermo-mechanical constitutive model consistent with the principles thermodynamics is presented. capable predicting rate-independent behavior fine-grained soils. equations are derived by defining only Gibbs-type free energy and dissipation potential, in accordance hyperplasticity method. addition thermo-elasticity to embedding identified mechanisms into newly proposed enables describe behavior. potential eliminates application shift stress, which results simpler context hyperplasticity. step-by-step procedure deriving equations, as well detailed analysis parameters model, performance shown be good agreement experimental data. A qualitative description possible micro-scale for soils, when subjected temperature variation, presented, step towards including formulation.
