Fatigue properties of vibration damping sheets of steel-resin lamination type were studied in connection with the effects of shear adhesion strength, tensile strength of steel sheets and thickness of vibration damping sheets. Fatigue tests were carried out under the conditions of shear by tension loading and out-of-plane bending.
Principal results obtained in this study are as follows:
(1) Fatigue strength in shear by tension loading increased in proportion to the increase in shear adhesion strength.
(2) Fatigue strength in out-of-plane bending showed a tendency to increase with increases in shear adhesion strength, tensile strength of steel sheets, and to increase with a decease in thickness of vibration damping sheets.
(3) Separation life under out-of-plane bending condition was estimated using fatigue test data under shear by tension loading. The estimated separation life showed a good agreement with the experimental result.
(4) An analytical method to estimate fatigue failure modes under out-of-plane bending condition, i, e. (1) fractured, (2) separated, and (3) not fractured nor separated, was proposed.
