Development work of GPFEM code and its application to soil-root interactions. Emphasis in homogenized continuum models. An elasto-plastic constitutive model in the framework of Critical State soil mechanics will be proposed in which the presence of roots will be taken into consideration in a continuum approach. The reference model, an enhanced version of the CASM model (Yu, 1998) for unsaturated soils, will be extended so the yield surface size depends on both the suction of the soil and the reinforcement by plant roots (Switala et al, 2019). The progressive failure of roots due to straining, causing a progressive deletion of the reinforcement effect of roots, will be incorporated through a set of new hardening laws.
The deadline for registration to the offer ends on October 30th, 2023 at 12 noon.
