What should you pay attention to when using a universal tensile test machine? Things to note when using a universal tensile test machine

The universal tensile testing machine exerted force on the sample. Special tests for tensile, bending, compression or shear are classified according to the direction of strain induced in the sample and the speed of force applied. The basic test is completed by a standard universal tensile testing machine. They are usually loaded in the speed range of 0.1mm/min to 500mm/min, and different materials require different test speeds. Dynamic and cyclic tests such as rupture growth and fatigue are generally completed over a long period of time and need to be completed on a servo hydraulic electronic tensioner with low loads.

Early universal tensile testing machines had pointers and chart recorders. They are now completely replaced by CNC and computer software. The new controller can automatically test and display the corresponding data. Even the stress and strain curve can be displayed instantly during the test. Reduced the workload of the experimenter's calculations.
