NIOSHTIC-2 Publications Search - 10007653 - Evaluation of a

This report presents results of a U.S. Bureau of Mines study of a punch shear test device for the direct evaluation of the shear strength of rock core. Sixteen sets of laboratory tests were conducted· under varied test conditions. Results were analyzed using factorial analysis and graphical methods.


A shear test device for rock mass discontinuities under constant normal stiffness conditions, comprising, a base used for placing a test piece; a loading framework fixedly connected with the base; a shear loading system arranged on the base and used for applying a shear force to the test piece; a normal loading system fixedly connected with the top end of the loading framework and used for applying a normal pressure to the test piece; a normal displacement monitoring system used for |||

Pocket Shear Vane Device - Utest Material Testing

The UTS-0088 Pocket Shear Vane Device is a practical equipment for determining the shear strength of cohesive soils. It is widely used to perform onsite measurements of excavations covering trenches and test pits, thin-wall or split core samples, by providing a quick and efficient method for shear strength measurements and it is also suitable for laboratory usage.

Shear Test Machines - TestResources,

Shear test machines are universal testing machines specially configured to evaluate shear strength or maximum shear stress_ A shear test is performed when shear forces cause one surface of a material to move in one direction and the other surface to move in the opposite direction so that the material is stressed in a sliding motion_

Direct shear test- Procedure, Calculation, and drawback of

Various methods can be implemented to determine the shear strength of soil material under various conditions, Among which one of the most common and simplest methods is the direct shear test using shear box apparatus which can be used to determine the shear strength parameters, cohesion (c), and internal angle of friction (φ) under various normal stress and shear strain rate conditions,
