LI Chong-yang, DU Xiao-song, JIANG Ya-dong, et al. Fabrication and applications of ytterbium stress gauges[J]. 2008, (2): 4-7. DOI: 10.13873/j.1000-97872008.02.038.
In the measurements of dynamic stresses ranging from tens of MPa to 2GPa
ytterbium stress gauge has high piezoresistance coefficient and it can be embedded in target materials.The ytterbium gauge exhibits excellent properties in investigating the propagation and attenuation phenomena of shock wave in rocks
soils
liquid mediums and structural materials.The research works of ytterbium gauges are summarized.The applications of these gauges in detonation
projectile penetration
high speed impact and high energy laser beam irradiation are presented.Some unresolved problems are also identified.
