| Sensitivity of Flow Curves to Thermo-Dynamical Parameters and Chemical Environment H2O and Pore Fluid Pressure Water in rocks acts as a softening agent as an equivalent amount of deformation to a dry sample at high stress can be achieved on a wet sample at lower differential stress (bottom left figure). Pore fluid pressure acts against the confining pressure and therefore promotes failure at lower differential stress and lower strain (figure on the right). |
