  1. Secondly, two carbon fiber reinforced composite beams were fabricated, and their modal frequencies were measured by an experiment method. thirdly, delaminations were modeled by pairs of nodes with the same coordinates but different node numbers, while the modal frequencies of these beams with different delamination location and size were computed by an eas piezoelectric solid element. moreover, a novel method combining computational mechanics and neural network was demonstrated for composite health monitoring ; the first five flexure modal frequencies obtained by fem were modified by a primary revising approach and were used to train the neural network

    本文較全面地評述了神經網路的應用模型、改進演算法等，編制了bp神經網路程序：制備了纖維增強復合材料試件，並進行實驗模態分析；利用坐標相同、節點號不同的方法模擬脫層損傷，基於eas列式的壓電固體單元計算了不同脫層損傷情況下的頻率信息；針對基於實驗數據訓練神經網路存在樣本不足的缺陷，本文提出了利用有限元方法對含有脫層損傷的復合材料試件進行數值模擬，以前五階彎曲模態頻率構建訓練樣本的新思路，並提出了一種初步的計算值修正方法，以此構建神經網路的訓練樣本：將實驗模態分析的結果送入訓練好的神經網路進行預測，實現了對復合材料梁的脫層損傷的定位和損傷程度的評估。
  2. On the basis of earthquake - resistant behavior experiments of high strength concrete column reinforced with concrete filled steel tube, two methods for calculating flexural strength of the column, one is based upon the method in building code for calculating the flexural strength of reinforced concrete member while the other is based upon the method of superposition, are discussed, and the moment ? xial load relationship is also analyzed using finite element method. the results are in good agreement with the experimental ones

    本文在以鋼管混凝土為核心的高強混凝土柱（鋼管高強混凝土核心柱）的抗震性能的試驗基礎上，分別基於鋼筋混凝土構件的規范計算方法和疊加法兩種思路討論了核心柱的正截面強度計算，並用條帶有限元方法模擬了核心柱的彎矩? ?軸力相關曲線，與試驗結果符合較好。
  3. The method removes the bottleneck of transformation from complementary energy element with stress functions vector to potential energy element with simple displacements vector. what is the most important about this method is that it never destroys the original convergence of the transformed plane elasticity element and that it can maintain the original precision

    本文方法列式簡單，所得板彎曲單元皆可通過常曲率分片試驗、有正確的剛體運動模式並具有與原始平面彈性單元相稱的良好精度，從而達到了將平面彈性單元轉化為板彎曲單元的目的。
