Strain Controlled Direct Shear Apparatus Three Speed

Strain Controlled Direct Shear Apparatus Three Speed

Strain controlled direct shear apparatus is used to determine the shear strength.
Shear strength is applied at different vertical pressures and thus shear is performed to obtain shear strength values.
The strength parameters are determined according to the Coulomb force principle and the cohesion from inside friction angle.
