2. Introducion The Torsion test lab was performed on a Schemaic of Technovate torsion test machine. The torsion test machine was used to test on 6061-T6 aluminum and s1018 cold rolled steel specimens by placing angle twist on the specimen unil it breaks and from there using measurements data to calculate for the total torque. Introduction. Torsion test is carried out to determine the shear modulus of structural materials, such as steel and aluminum. Shear modulus is a material property that is useful in calculating the compliance of structural materials in torsion, provided that they follow Hooke’s law; that is, that the angle of twist is proportional to the .ME 354 LAB #4: DISCUSSION OF THE TORSION TEST Each lab section performed a torsion test of a cylindrical 6061-T6 aluminum specimen.

Axial-Torsion: Applying both axial (tension or compression) and torsional forces to the test specimen. Failure Testing: Twisting the product, component, or specimen until failure. Failure can be classified as either a physical break or a kink/defect in the specimen.The torsion test is a mechanical test method used to examine the deformation of a specimen through a twisting/rotating motion.. Torsion, in its simplest form, is the action of twisting. Many everyday materials, components, component .Introduction. In a torsion test, a test specimen is twisted to a specified angle with a predetermined force, or until failure occurs. Torsion testing is used to examine how a material or test sample behaves when twisted or subjected to torsional stresses as a consequence of applied moments that create shear stress along the axis.
