Non-destructive Testing of Bolts by Stress Reflection Wave Method Considering Frequency-domain Curve
The nondestructive testing of bolt integrity by stress reflection wave method is based on one-dimensional stress wave theory,which focuses on the analysis of stress wave velocity variation in media.So far,the acceleration curve analysis is widely used in the industry.In this paper,the author compares the analysis results of the acceleration curve and the velocity curve with the concrete engineering case and the standard bolt model,it is suggested that the analysis of bolt integrity should be combined with the comparative analysis of acceleration curve,velocity curve and corresponding frequency-domain curve.
