Numerical Simulation of the Rock Bolts Non-Destructive Testing Based on ANSYS


Article Preview

A numerical simulation method of the rock bolts non-destructive testing based on ANSYS is presented. ANSYS/ LS-DYNA which is a kind of software of rock bolts dynamic finite domain analysis is used to establish a three-dimension model, after sine curve excitation is loaded, the reflection curve of naked rock bolts, or rock bolts with different defects are got, and the relationship curve between elastic modulus and stress wave velocity are got correspondingly. Experiment result proved that the aboved method was satisfied to simulate the stress wave propagation and the reflection situation in the rock bolts.
