Robust assessment of shear parameters from direct shear tests [PDF]
In the geotechnical determination of the cohesion c and the angle of internal friction φ of a soil from shear tests, a linear regression model is fitted to normal and shear stress data, and confidence bounds are computed. The applicability of standard linear regression is limited by the physical requirement of non-negative cohesion and the statistical ...

Characterization of peak shear strength of rough rock joints using limited displacement multi-stage direct shear (LDMDS) tests [PDF]
Current standard direct shear test methods for rock joints do not account for damage to the specimens' asperity profiles; tests require shearing of a single specimen to large displacements under successive normal stresses (the multistage test), or the ...

Application of in situ direct shear device to shear strength measurement of rockfill materials
A simplified in situ direct shear test (DST) was developed for measuring the shear strength of soils in fields. In this test, a latticed shearing frame replaces the upper half of the shear box used in the conventional direct shear box test.
