...% quartz) and basalt (0% quartz) during triaxial deformation. An increase in electric potential occurs during deformation for both dry and saturated sandstone and basalt. The relationship between electrical potential change and axial stress is linear for dry sandstone and dry basalt as expected from...

... sandstones can be approximated by the Morita model are given. By the reformulation of the model, we have cut the time required to set up a parameterisation drastically, and the final model is to a smaller degree dependent on the skills of the engineer. The model is found to be able to match the axial stress...
