Effect of the Surface Roughness on the Shear Strength of Granular Materials in Ring Shear Tests [PDF]
Applied Sciences, 2019 Surface roughness plays an important role in estimating the shear strength of granular materials. A series of ring shear tests with different surface roughnesses (i.e., smooth and rough surfaces) were performed.

Suction-controlled ring shear test of the silt and concrete interface [PDF]
Frontiers in Earth ScienceThe interface of a structural system in the soil is usually unsaturated. A decrease in the shear strength of the soil-structure interface can degrade the structure, especially under humid conditions.

Shear characteristics of over consolidated peat in constant volume ring shear test
Jiban Kogaku Janaru (Japanese Geotechnical Journal), 2008 正規圧密および過圧密された高有機質土に対して定体積リングせん断試験を行い，これまでの三軸試験を通した検討では見られなかった高有機質土のせん断特性の一端を明らかにしている。先ず，定体積リングせん断試験では高有機質土でもせん断応力にピークが現れ，その非排水せん断強さは明確に決定できることを明らかにした上で，破壊時の変位量は圧密圧力や過圧密比に依存するものの，間隙比との間には一義的な関係にあること，せん断初期の応力～変位関係は双曲線で近似でき，その漸近線が示す応力とピーク強度の間には比例関係が認められること，正規圧密試料でも圧密圧力～強度関係は原点を通らないこと，かつ，得られる強度増加率は三軸圧縮試験による値より小さいこと，また，せん断抵抗角も三軸圧縮試験から得られる値よりかなり小さいこと，さらには ...
