WebAug 3, 2016 · Section 9.4 provides instruction for standardization of the internal temperature detector of the DSR. The user may perform this standardization using either a silicone rubber wafer (Section 9.4.1) or a temperature probe inside a dummy test specimen (Section 9.4.2). In either case, the DSR’s temperature detector must be standardized at 6°C ... WebOct 1, 2024 · Shear slip of rock joints under dynamic disturbance is a major factor causing disasters such as landslides and cavern instability. To explore the dynamic shear deformation behaviors of rock joints, an impact-induced direct shear test applicable for jointed rock specimen is conducted.
