Figure 5: BASQUIN Fatigue curves for different / ratios – Mean and probabilized curves 5.2. Residual tensile force Erreur ! Source du renvoi introuvable. shows the representation of the fatigue curve specific to non-metallic materials. This schematic curve clearly shows the loss of allowable load in fatigue.

Maximum tensile strength (number of bending fatigue cycles equal to 0)

Duration levels = stop for a given number of cycles + tensile test to determine residual tensile strength

Residual tensile strength [N]

Fatigue failure

Number of bending cycles to failure
