Constitutive simulation of a Kaolin clay with vertical and horizontal sedimentation axes
Experimental observations indicate that the mechanical behavior of clays is not only dependent on the stress and void ratio, but on its inherent anisotropy. The latter is the one arising from the material sedimentation process. In this work, the inherent anisotropy of a Kaolin clay is studied. For t...

| description | Experimental observations indicate that the mechanical behavior of clays is not only dependent on the stress and void ratio, but on its inherent anisotropy. The latter is the one arising from the material sedimentation process. In this work, the inherent anisotropy of a Kaolin clay is studied. For this purpose, soil samples are prepared with a proposed method producing samples with horizontal and vertical sedimentation axes. The samples go thru permeability tests, unconfined compression tests, oedometric compression tests and direct shear tests and the results carefully analyzed from the constitutive modeling point of view using the hypoplastic model for clays by [1]. Later, identify parameters depending on the inherent anisotropy; then perform some simulations to evaluate the model performance upon different samples with vertical and horizontal sedimentation angles. At the end, some concluding remarks are given. |
