영문 초록

Simple equations which can predict “exact” values of the natural frequency of vibration for the special orthotropic laminates are presented. Many laminates with certain orientations have decreasing values of B₁₆ and B₂₆ as the number of plies increases. Such laminates, with B₁₆ = D₂₆→0, including the laminates with anti-symmetric configurations can be solved by the same equation for the special orthotropic laminates. If the quasi-isotropic constants are used, the equations for the isotropic plates can be used. Use of some coefficients cab produce “exact” value for laminates with such configurations. Natural frequencies of the plate with varying aspect ratios is presented.
