Fatigue performance

According to BS 4449:2005-A3:2016 Fatigue test is carried out on full section bars using a sinuso dal tensile load as follows:

Diameter, mmMax. stress,mpaMin. stress,mpaNo. of cycle
>16250505.0 million
2231465.0 million
25212425.0 million
32200405.0 million
40187.537.55.0 million
50187.53755.0 million

All tests are required to survive for 5 million stress cycles under these loading conditions. The procedure is carried out at room temperature with a frequency of up to 200Hz.

The test is continued until 5 million stress cycles have been reached or until the fracture of the test sample.
