Abstract: A yong' s modulus formulas which is suitable for me asuring the second isotropic by dispersion wire couple bending resonance method has been deduced .The calculating shows that the result is the same as reference〔2〕at h2/ h1 ≈1 .A formulas is suggested for measuring yong' s modulus of vibration -damping materials and ceramic materials by dispersion wire couple bending resonance method .At the same time, a predicting formulas which is suitable for fiber composite Er has been deduced from bending model .

Keywords: yong' s modulus, metal matrix composite, fiber composite, dispersion wire couple bending resonance method
