Torsion Tester Machine

Torsion TestMethod for determining behavior of materials subjected to twisting loads. Data from torsion test is used to construct a stress-strain diagram and to determine elastic limit torsional modulus of elasticity, modulus of rupture in torsion, andTorsional Strength. Shear properties are often determined in a torsion test. (ASTM E-143)Torsional StrengthMeasure of the ability of a material to withstand a twisting load. It is theUltimate Strengthof a material subjected to torsional loading, and is the maximum torsional stress that a material sustains before rupture. Alternate terms are modulus of rupture and shear strength.
