(2018) 25: 653-661 DOI: https://doi.org/10.1007/s11771-018-3768-x Degradation of joint surface morphology, shear behavior and closure characteristics during cyclic loading FAN... parameters of the rock joint surface were precisely calculated by means of a three-dimensional laser scanning machine. All test results were analyzed to investigate the shear behavior and normal displacement......
Fractography The SEM image of the fracture surface shown in Figure 11(a) corresponds to the parameters 500 r/min rotational speed, 100 mm/min traverse speed and STTP tool profile. Figure 11(b) represents the fracture surface of the parameters 500 r/min rotational speed, 100 mm/min traverse speed and TTP tool profile. This comparative analysis explains the failure pattern by dimples......
