Detailed explanation of the test process of material torsion testing machine for brittle materials

Material torsion test machineTorsion tests can be performed on a variety of materials. The following test methods are a detailed explanation of the process of Jinan Hengsi Shanda Instrument Co., Ltd. for brittle materials testing, for customers to understand:

Material torsion test machineIt is a test to test the effect of the sample against torque. It is one of the basic test methods for the mechanical properties of metal materials. The specific method is to apply a torque at both ends of the gauge distance of the cylindrical sample during the test. At this time, a torsion angle is generated between the two sections of the gauge distance of the sample. A torsion diagram can be drawn according to the changes in torque and rotation angle. At the same time, the corresponding stress and strain diagram can be obtained. Μp corresponds to the torsion proportion limit τp; Μ0.3 corresponds to the torsion yield strength τ0.3 (Explanation: stress when 0.3% residual shear strain is generated); Μb corresponds to the torsion strength limit τb. The fracture shape of the torsional specimen can reflect the material properties and stress conditions. For example, the section of the fracture is perpendicular to the axis of the sample, and the material is plastic, which is the result of the shear stress action; for example, the section of the fracture is about 45° angle to the axis of the sample, and the material is brittle, which is the result of the normal stress action.
