Abstract
The mechanical behavior of soils is typically interpreted based on their response to applied stress during shearing. Several hyperbolic stress-strain relationships have been developed for use in non-linear incremental analysis of soil deformations. It is noted that the bulk electrical resistance of the soil changes with respect to its deformation. This phenomenon reveals the possibility of modeling deformation behavior of the soil based on changes in bulk electrical resistance. This paper proposes a methodology to model stress-strain behavior of the soil under unconfined load by using the change of bulk electrical resistance of the soil. A hyperbolic model was developed in which the change of stress is predicted based on the change of electrical resistivity of soil cylinder during axial deformation. This approach predicts the entire deformation process of the soil under unconfined compression load, without needing to conduct an entire unconfined test.
