System introduction
Hollow cylinder torsional shear tester is fully automatic control of multi-functional testing equipment, servo motor can independently control the axial force, torque, internal pressure, peripheral pressure, back pressure. It can simulate most dynamic and static stress-strain path tests, including plane strain, shear, principal stress rotation, true triaxial, etc. The maximum frequency is 5Hz, and the automatic test is realized through Smartlab, the comprehensive geotechnical testing software developed by the master. Users can also customize the test.
