Reliable in-situ strength information is critical for construction-stage decisions, yet conventional UPV–UCS correlations are typically established on companion cylinders, which may overestimate the ...

Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickness or internal structure of a test piece using high-frequency sound waves. The ...

Figure 1. Ultrasonic testing using pulse echo and through-transmission methods. Pulse echo (left and center) uses a transducer that sends and receives ultrasound energy, producing both A- and B-scan ...

Figure 1. Industrial LEA-based inspection system in production use for automated helicopter tailboom inspection. Inset: the laser-based ultrasound generation unit of the through-transmission ...

A new ultrasonic test method can acquire high-resolution shale data in the lab by using new geometries for sample testing with specialized equipment suited for measuring shale formations at reservoir ...
