Abstract

Innovative energy-based coupled elastoplastic hybrid isotropic damage-healing models for partially saturated soils have been developed and implemented for numerical simulation of soil moving processes. A class of elastoplastic constitutive damage-healing models, based on a continuum thermodynamic framework, is proposed within an initial elastic strain energy-based formulation. In particular, change of effective stress due to matric suction is considered, and the governing incremental damage and healing evolutions are coupled and characterized through the effective stress in conjunction with the hypothesis of strain equivalence. Further, plastic flow is introduced by means of an additive split of the stress tensor. Two characteristic energy norms of the tensile and compressive strain tensors, respectively, are introduced for the corresponding damage and healing mechanisms.

By incorporating micromechanics-motivated damage and healing characterizations, the proposed model and computational algorithms have been implemented to demonstrate the significant flexibility on numerical simulation of earth-pushing processes. Completely new computational algorithms are systematically developed based on the two-step operator splitting methodology. The elastic-damage-healing predictor and the plastic corrector are implemented within the existing RKPM (Reproducing Kernel Particle Method) meshfree codes. A numerical example under soil pushing is presented to illustrate the effect of matric suction for partially saturated soils.
