    纖維織物增強復合材料微觀應力場的有限元分析
  2. Analysis results of histogram statistics and section electron microscopic scan technique, are that fracture feature of the cracks of the hbbb is similar and the crack is multi - source strain fatigue one. internal defects of the cast, such as impurities, gas holes, etc, are the main causes for early cracks. the contrast analysis of static strength, model and transient respond on three structures with fem proves that geometrical stress concentration in partial area has influence on early crack, also

    利用直方圖等統計方法和電鏡掃描技術對該抱軸箱體裂紋分析的結果是：抱軸箱體的裂紋斷口特徵相近，裂紋性質屬于多源性低周疲勞裂紋，鑄件中的夾雜、氣孔等內部缺陷是導致過早裂損的主要原因；利用有限元法對該抱軸箱體三種結構的靜強度、模態和動態響應對比分析，證實了局部幾何性應力集中對過早裂損也有一定影響。
  3. Presents the investigation of the heat conduction behavior, internal thermal stress field of specimen under thermal shock and microscopic damage and failure of the tungsten based composites by combination of macroscopic and microscopic analyses and integration of material science and mechanics ; describes a microscopic mechanical model based on the microstructure of components with macroscopic stress applied to the microscopic model as that of maximum principal stress at the center, and the fringe of the specimen, and the microscopic stress fields obtained through calculation by the finite element method, and concludes from test results that the maximum principal stress is first generated inside the test coupon, and a failure will be first initiated in the inclusion if the material fails at this time ; the maximum principal stress moves to the edge of the test coupon after the test coupon is heated for a period of time, and the failure will first be initiated in the base if the material fails at this time

    從材料設計的思想出發，採用宏觀與微觀、材料科學與力學相結合的方法，對鎢基復合材料的熱傳導行為、材料在熱沖擊載荷下的內部熱應力場及材料細觀結構的破壞行為進行了詳細的理論研究.根據鎢基復合材料的細觀組織結構建立了材料細觀模型.在宏觀分析的基礎上，分析了材料微結構內部的破壞行為.分別取試件心部與邊緣主應力值最大點的應力狀態，施加在所建立的模型上，用有限元方法計算了模型內部的彈性應力場.結果表明：試件主應力最大值首先產生在試件內部，此時，如果材料發生破壞將先從夾雜中開始；加熱一段時間后試件中的最大主應力值轉移到試件邊緣，此時材料發生破壞將先從基體中開始
  4. The microscopic plastic deformation of the local crazes cause the change of crack opening loads. therefore, the fatigue crack closure concept could be introduced. a crack closure model of mdyb - 3 pmma were recommended and phenomenologically formulated for positive and negative stress ratios separately, according to the testing results of fatigue crack propagation

    本文討論了有機玻璃疲勞裂紋擴展機理，提出，銀紋的形成是裂紋形成和擴展的基礎，從微觀上解釋了裂紋形成和擴展的原因，並結合金相分析結果，明確提出塑變誘導閉合和粗糙誘導閉合是有機玻璃疲勞裂紋面閉合的兩個主要原因，成功的解析了裂紋面的閉合現象。
  5. The results of visual inspection, microscopic inspection and corrosion product analysis revealed that stress corrosion was the main cause of the grid collapse
