Abstract: By taking unsymmetrically angleply laminated plates of anisotropic composites as an example to make an analysis of tha complete solution analysis process (including calculating examples) of non-linear flexural forced vibration of plates under the harmonic force,the writers obtain amplitude-frequency relationship of anisotropic unsymmetrically angle-ply laminated plates under the load of different-magnitude,and the effect of the change in plying layers of laminated plats upon the amplitude-frepuency relationship of non-linear flexural forced vibration.The solution analysis result thus obtained is reliable and the conclusion drawn from the result is representative.What has been done so far is undoubtedly a meaningful attempt in the matter of non-linear dynamics of anisotropic laminated plates and will be a great help in the further research of some other note-linear dynamics of anisotropic laminated plates.
