Torsional Strength Assessment Test
The Torsional Strength Assessment Test is a critical evaluation method used to determine how materials and components withstand applied torsion. This test is pivotal in ensuring that materials intended for use in additive manufacturing (AM) and 3D printing meet the necessary strength requirements under rotational stress.
In the context of raw material characterization, this test plays a significant role in assessing the suitability of various materials used in AM processes. The torsional strength assessment helps identify potential weaknesses or strengths that could impact the overall performance and longevity of parts manufactured through additive manufacturing techniques. This is particularly important given the complex geometries and stress concentrations often found in 3D-printed components.
The test involves applying a controlled torque to the specimen, measuring its resistance until failure occurs. The key parameters include the applied torque increment, the speed at which it is increased, and the recording of any deformation or fracture that leads to failure. The results provide insights into the material's shear modulus (G), yield strength, and ultimate tensile strength in torsion.
Standard testing procedures for this assessment follow international standards such as ISO 17826:2019, which provides a guideline for the determination of torque-torsional angle relationship. Compliance with these standards ensures reliability and consistency across different laboratories and facilities.
