Description
The SHEARTEST-300 is a versatile and sturdy direct-shear system. This advanced, closed-loop, servo-controlled device utilizes hydraulic actuator to simultaneously apply normal and shear forces to a rock sample within a specimen shear box. A dedicated computing station records shear and normal displacements as well as forces. Subsequently, these recorded data are employed to determine the shear strength characteristics of the rock, which include cohesion (c) and friction angle (Ø).
