Abstract
提出了兩種分別適用於板的面內振動和圓環板彎曲振動模態分析的Fourier級數形式的插值形函數。數值計算結果表明 ：對於結構振動模態分析, Fourierp_單元法能夠有效地提高計算精度及收斂速度, 特別是對於較高階的模態效果更為明顯。
Two kinds of Fourier version shape functions are constructed, which are suitable for plate in-plane vibration and annular plate vibration mode analysis, respectively. Numerical results show that for structure mode analysis Fourier p-element method can achieve high accuracy and converge very fast, especially for higher modes.
