Description
The AVS-0 system allows for the propagation of compressional and shear waves through rock specimens under overburden pressures of up to 10,000 psi and at ambient temperature. It computes the acoustic velocity and ascertains dynamic elastic constants. This computer-controlled setup comprises an acoustic triaxial cell, a compression testing frame, and a fast-acting pulser-receiver responsible for both exciting the ultrasonic sensors and displaying the resulting waveform signals. The rapid-response pulser is utilized to initiate the excitation of the ultrasonic sensor integrated into the platens of the triaxial cell, while an exceptionally high-speed analog-to-digital converter is employed for the swift capture and storage of the ensuing waveform signals.
