(dynamic) (r) the number of deformations required to produce a specified state of fatigue breakdown in a test piece or product that is deformed under a prescribed set of conditions.

The number of cycles the will cause failure at a certain stress level

Physical Properties and Testing Number of stress cycles required to bring an adhesive bond to the point of failure when the bond is subjected to repeated cyclic stressing under specified conditions.

Number of cycles of fluctuating stress and strain of a specified nature that a material will sustain before failure occurs. Fatigue life is a function of the magnitude of the fluctuating stress, geometry of the specimen and test conditions.

The number of cycles of stress that a band tool can sustain prior to failure for a stated test condition.

See Cycle Life.

The number of cycles of stress that can be sustained prior to failure under a stated test condition.

Number of deflection cycles until failure occurs at a predetermined stress.
