Stress amplitude
Stress range between mean and maximum stress during cyclic loading.
Opening sensor; crack opening displacement extensometer
Extensometer sensor which, by measuring the aperture between the two blades of the sensor, enables the length of the propagated crack to be determined using the complacency method.
Mean stress
Average stress level on a cyclic signal.
Curbe d'écrouissage cyclique; cyclic stress-strain curve
Relationship between maximum strain imposed and maximum stress reached with a strain ratio equal to – 1.
Manson-Coffin curves; EN curves
Relationship between plastic, elastic and total strain amplitude as a function of the number of cycles to...
