Scope

This part of GB/T 37306 specifies the general rules for the cyclical fatigue test of laboratory samples for each cycle of amplitude variation.
This section specifies and gives general rules for variable amplitude fatigue tests to generate for comparison when considering the typical dispersion of fatigue data.
Consistent results.
This section is theoretically applicable to strain and force control or loading conditions for controlling fatigue crack growth rate, using this part of the loading
Mode, not force - Appropriate protection should be taken when controlling the loading mode.
This section applies to single actuator loading mode for single axis loading.
The variable loading time history referred to in this section is deterministic, which is why this part deals with variable amplitude loading rather than random loading.
The following items are outside the scope of this section.
--- Constant amplitude fatigue test with isolated overload or underload phenomenon;
---Experiment of large parts or structural parts;
--- Environmental impacts such as corrosion, temperature/time related creep leading to effects on frequency and waveforms;
--- Multi-axis loading.
