GB/T 40410-2021 Multi-axial fatigue test of metal materials axial-torsional strain control method

2022.01.13  

     This document specifies the principle, sample, test equipment, test procedure, data processing analysis and test report of axial torsional composite fatigue test of metal materials under strain control。

     This document is suitable for metal thin-walled tube specimens under room temperature and high temperature loading waveform with constant amplitude symmetry and zero average strain and axial torsion composite fatigue test with the same frequency of axial and torsional waveforms。

     As a drafting unit, Shenzhen Wanyi participated in the drafting of this standard。Wanji's electro-hydraulic servo torsion fatigue testing machine and electronic servo torsion fatigue testing machine are suitable for this standard。

     Electro-hydraulic servo torsion fatigue testing machine is mainly to do the reciprocating torsion fatigue test of shaft samples, the test object can be metal, non-metal, composite materials and other material samples, it can also be the structural parts of the shaft, such as automobile drive shaft and so on。The test environment can be room temperature, high temperature, low temperature, salt spray and other environments (need additional environmental tank)。
