Observations of Projectile Penetration into Transparent Soils

A transparent sand surrogate was employed along with high-speed imagery to un-intrusively visualize the penetration of a spherical projectile into the middle of a saturated granular target, representing angular sand, at speeds ranging between 60 and 150 m/sec. The transparent sand was made by saturating an angular fused quartz waste product with a matched refractive index pore fluid made of sucrose. A distinct zone of opacity was observed travelling ahead of the projectile. Some healing was also observed with time and some increase in transparency was observed. Some of the opacity is attributed to dilatency of the fused quatz during penetration, and healing is attributed to flow of pore fluid into the dilated zone.

A great scholar having strong insights and work on TSM👍

Thanks for your video! I want to ask how to make trasparent soil for sand?
