In addition to tests on artificial ball-and-socket joints and bone .Torsion Testing Equipment. Torsion testing can be performed on any one of several different testing systems depending on the specific application. Some labs prefer a dedicated torsion-only testing system such as Instron's MT MicroTorsion Series, while others may prefer to adapt their existing universal testing machine with a Torsion Add-On 3.0 fixture that enables the system .
A torsion test is a mechanical testing method that evaluates the properties of materials or devices under stress caused by angular displacement. During a torsion test, a specimen is subjected to a twisting or torsional force, which induces a torque. This test is used to measure various mechanical properties of materials, including their modulus of rigidity, shear stress, .
