Effects of pore collapse and grain crushing on ultrasonic ...

microstructural observations that grain crushing in sand-stone is generally characterized by extensive microcracking as cracks nucleate and propagate when pressure reaches the critical pressure P*. Therefore these newly formed cracks may induce a decrease in elastic wave velocities. Second, Zhang et al. [1990], Wong et al. [1997], and Karner et al.

Ultrasonic Sensing Basics (Rev. C)

2020-3-26 · Ultrasonic sensors can detect a variety of materials, regardless of shape, transparency, or color. The only requirement for ultrasonic sensing is that the target material is a solid or liquid. This enables contactless detection of: • Metal • Plastic • Glass • Wood • Rocks • Sand • Oil • Water • Other hard, non-sound absorbent materials
