Figure 9From: Mechanical and hydraulic behavior of a rock fracture under shear deformationRelation between electric conductivity and measurement time in the tracer tests. The t - R relation at the entrance and exit in the acrylic specimen was found parallel to each other and shows the Hagen-Poiseuille flow. On the other hand, the t-R relation in a rock specimen shows a time delay in the curve because the complex pore structure caused selective flows.Back to article page
