Robust assessment of shear parameters from direct shear tests [PDF]
International Journal of Reliability and Safety, 2012 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]
E3S Web of Conferences, 2019 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
Water Science and Engineering, 2009 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.
