Golchin, A. (author), Vardon, P.J. (author), Hicks, M.A. (author)The formulation of a new thermo-mechanical constitutive model consistent with the principles of thermodynamics is presented. The model is capable of predicting the rate-independent thermo-mechanical behavior of fine-grained soils. The constitutive equations are derived by defining only a Gibbs-type free energy and a dissipation potential, in...journal article 2022

Golchin, A. (author), Vardon, P.J. (author), Hicks, M.A. (author), Coombs, William M. (author), Pantev, I.A. (author)The numerical implementation of a recently developed thermomechanical constitutive model for fine-grained soils based on hyperelasticity-hyperplasticity theory (Golchin et al. 2020), is presented. A new unconventional implicit stress return mapping algorithm, compatible with elasticity derived from Gibbs (complementary) energy potential, in...conference paper 2021
