Figure 4From: Frictional properties of the shallow Nankai Trough accretionary sediments dependent on the content of clay mineralsFriction coefficient μ plotted against sliding displacement d for gouges of five samples tested in this study. The sequence of steps in axial displacement rate (Vaxial) is shown only for sandstone sample 2571, but the same sequence was applied to all the other samples. See Table 3 for experimental conditions.Back to article page
