Coefficient de sécurité; Safety factor
Ratio between the value of a stress causing a failure and the value of the operating stress stipulated by regulations, for example.
Residual stress; Contrainte résiduelle
Represents the state of stress (compression or tension) of a material when it is not subjected to any external load.
Low Cycle Fatigue (LCF)
Range below 10 4 to 10 5 oscillation cycles, determined by Low Cycle Fatigue (LCF) test.
High Cycle Fatigue (HCF)
Determined in the High Cycle Fatigue (HCF) test: the result is the number of oscillation cycles at a given load amplitude.
Very High Cycle Fatigue...
