Direct shear tests

The angle of internal friction and cohesion of the ASS mixes (1 6) obtained from the direct shear tests are in the range of 40 42 deg and 0.353 1.323 kPa, respectively

Direct shear tests on JSC-1A Lunar regolith simulant

From Fig. 8, it is clear that applying Eq. 6 produces a fit that closely matches the empirical data measured during direct shear tests.

the equations presented for shear strength and cohesion above are generally limited in their application to terrestrial atmosphere and gravity, with normal stresses <0.68 kPa, as these were explicitly

Direct shear tests were performed with four different vertical confinement levels (= 50, 100, 150, and 200 KPa).

Comparative study on morphological and mechanical properties of lunar regolith simulants (LHS-1, LMS-1, and LSP-2) using micro-CT reconstruction and direct shear tests

The direct shear tests conducted on the LHS-1E lunar regolith simulant at various moisture contents and under frozen conditions revealed apparent cohesion values ranging from approximately 6 to 8 kPa,
