Test parameter torsional strength

Introduction to test parameters:

The relationship between torque and torsion angle can be obtained by torsion test of cylindrical material. The maximum shear stress of corresponding maximum torque is called torsion strength. Function and purpose of instrument:

It is mainly used for torsion test of metal or non-metal materials, and also for torsion test of parts or components

Test basis: torsion test method of metallic materials at room temperature GB / T 10128-2007

Test parameter shear modulus

Introduction to test parameters:

Shear modulus is the ratio of shear stress to strain. Also known as shear modulus or rigid modulus. It is the ratio of shear stress to shear strain in the limit range of elastic deformation ratio under the action of shear stress. It characterizes the material‘s ability to resist shear strain. Function and purpose of instrument:

It is mainly used for torsion test of metal or non-metal materials, and also for torsion test of parts or components

Test basis: torsion test method of metallic materials at room temperature GB / T 10128-2007

Sample requirements: samples required in the standard

Note: the project has passed the laboratory accreditation and measurement certification

Yield strength

When the metal material appears yield phenomenon, the stress corresponding to the stress that the specimen will not increase but continue to deform in the test process should be distinguished between the upper yield strength and the lower yield strength.
