本文將高階層板有限元素法應用於雙模 數積層板的自由振動分析。將動能加入位能以 考慮慣性力作用,分析單層及兩層雙模數積層 板,本法得到很接近理論解的自然頻率與中性 面位置。很明顯地,本法因使用高階板理論之 故,可得到較一階板元素更為精確的結果。 The free vibration analysis of bimodulus laminated platesis established by using the higher-order plate element in this paper. The inertia effects are considered by adding kinetic energy to the potential energy. Several comparative examples include single-and two-layer bimodulus plates. The natural frequencies and neutral surface locations are determined. The numerical results are compared to the available analytical solutions, and excellent agreement is observed. Apparently, more accurate results than the first-order theory results are obtained herein.
