Predicting the fatigue life of woven fiberglass under steady and nonsteady cyclic loading
- 22 Downloads
Analytical expressions describing the kinetics of the damage parameter of the woven fiberglass during its fatigue failure are obtained for any level of steady cyclic load in the 38–70 MPa interval of stress amplitudes.
It is established that the critical value of the damage parameter D* in the stress-amplitude interval under consideration is independent of the stress level at which the specimen experiences fatigue failure.
Methods of computing the fatigue life of woven fiberglass under a nonsteady cyclic loading are developed.
Methods are proposed for the accelerated determination of the fatigue curve of woven fiberglass.
