  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件進行數值模擬,以前五階模態頻率構建訓練本的新思路,並提出了一種初步的計算值修方法,以此構建神經網路的訓練本: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。
