The effect of mean stress on the fatigue behavior of woven-roving glass fiber-reinforced polyester subjected to torsional moments
Article Abstract:
The effect of torsional mean stress on the fatigue behavior of glass fiber-reinforced polyester (GFRP) is studied by testing thin-walled woven-roving tubular specimens with two fiber orientations. The results indicated that the positive stress ratio points have the same local stress state while the negative ones showed an acceptable behavior tending to decrease the amplitude component for the same life.

Fatigue crack identification in tensile-shear spot welded joints by dynamic response characteristics
Article Abstract:
A theoretical model for the estimation of fatigue crack length of tensile-shear spot welded specimen is developed which incorporates the natural frequency and mode variation. The model is based on the concept of propagation of cracks causing a release of strain energy, which is related to the structural modal shape.

Three stages of fatigue crack growth in GFRP composite laminates
Article Abstract:
Fatigue failure in composite laminates involves combination of several damage modes including matrix cracking, delamination and fiber fracture. The results show that stable transverse fatigue crack growth rate is essentially independent of crack length but dependent on crack spacing.
