Measurement of the shear strength of snow using a bevameter and a hand-held shear device / by J. Y. Wong.: DR52-4/8-1990E-PDF
The shear data for snow covers in Fernie, British Columbia obtained using a bevameter and a hand-held shear device were evaluated and compared. It was found that the values of the shear strength parameters derived from data obtained using the hand-held shear device provided by Vehicle Mobility Section, Defence Research Establishment Suffield (DRES) were noticeably different from those obtained using the bevameter. The difficulty in controlling the normal load and the manual reading of the load gauge and spring scale contribute to the uncertainty concerning the reliability of the shear data obtained using the hand-held shear device. The reliability of the data obtained would be greatly dependent upon the skill of the operator. Furthermore, in operation, an external force and not a pure moment is applied to the torque arm to rotate the shear ring of the hand-held device.
