WebbA simple torsion test is relatively easy to perform. The angle of twist is measured on a specimen (with a circular cross-section) as an applied torque is increased at a constant rate. This is analogous to plotting the load and extension in a simple tensile test. Webb27 aug. 2024 · Torsion Testing . Torsion testing is another form of mechanical testing that evaluates a material’s behavior when subjected to stress at an angular displacement. As a result, it gives information about the material’s shear modulus of elasticity, shear yield strength, shear strength, shear modulus of rupture, and ductility.
