| Research Abstract |
The study on elasto-plastic behaviors of crushable and uncrushable soils with different grain size from the standpoint of continuum mechanics was conducted. Firstly, systematic experimental studies revealed that particle crushing induces decrease of the critical state line and remarkable plastic deformation. Additionally, elasto-plastic constitutive model was developed based on the experimental results, and applicability of the model was demonstrated.
