• A New Approach of Waveform Interpretation Applied in ...

    Due to the characteristics of dispersion of guided waves, the waveforms recorded in ultrasonic nondestructive testing (NDT) of rock bolts are complicated to interpret. With a goal to increase the inspection sensitivity and accuracy in NDT of rock bolts, an approach of waveform interpretation based on wave modes identification is developed. The numerical simulation of full rock bolt and rock ...

  • Chapter Introduction IITK

    The mechanical anchor bolt consists of a smooth bar with a threaded anchor end. A mechanical shell anchor attached to the threaded end of the bolt is used to anchor the system. When a torque is applied to the bolt, the force drives a plug against the outer shell, which then expands and sets against the rock in the borehole walls (Figure 22).
