Cumulative (AE) RDC plotted against deviator stress (kPa) measurements for load–unload–reload cycles of deviator stress (kPa) performed on LBS 1·0–2·0 at an effective confining pressure of 300 kPa and axial displacement rate of 6 mm/h. The inset shows deviator stress (kPa) plotted against time (test 16)
