Metal Tensile Test
Tensile Test
Adopting strain control in tensile tests is a highly scientific method, which can effectively control the test rate of the specimen itself and eliminate the influence of system deformation. GB/T 228, ISO 6892, and ASTM E21 all stipulate the rate for tensile tests, and strain rate control is recommended as a method, which places higher requirements on testing machines. The Youshi series electronic universal testing machines have a closed-loop control rate of up to 2500 Hz, and with precise PID parameter adjustment, they can more accurately complete tensile strain control tests for different materials. For strain measurement, clip-on extensometers, automatic extensometers, video extensometers, etc., can be selected, all of which can realize the function of strain control. # Strain Rate vs. Time Curve The more advanced and scientific extensometer-based strain rate control method adopted in metal tensile tests has been recognized and supported by more and more professional test personnel. The Lishi Youshi series electronic universal testing machines have a closed-loop control rate of up to 2500 Hz, and with precise PID parameter adjustment, they can
more accurately complete tensile strain control tests for different materials.
