By means of the calculation results of interlaminar stress distributions, the influence of delamination growth on the resultant fatigue lives is qualitatively discussed, realizing that a more comprehensive analytical model is essential to include the effect of stacking sequence and the arosing interlamina stresses on fatigue behaviors of laminates. the recommended scheme was also used to calculate the fatigue lives of specimens with central holes subjected tensile - compressive cyclic loadings and has got comparable estimations with experimental results
發現和修正了有關文獻中的一些錯誤，重新建立了斷裂筋條彎曲修正的公式和位移協調方程，編制了相應的計算程序，根據計算結果探討了斷裂筋條和筋條彎曲對蒙皮裂紋的影響，指出了有的文獻上給出的計算曲線存在的謬誤。 -
In this dissertation, the effect of texture, heat - treatment, and hydrogen on the lcf behavior of zircaloy - 4 and the cyclic deformation behavior for zircaloy - 4, n18 alloy and n36 alloy have been investigated systematically using fully - reversed tension - compression loading under strain control ( r = min / max = - 1 ), while the evolvement of the friction and back stresses versus the number of repeated working cycles and the plastic strain amplitude has been studied, and the thorough discussion combined with the analysis result of fatigue sub - structure, friction and back stresses, and fatigue fracture has been given to the mechanism underlying the lcf behavior of alloys
本文採用對稱拉壓循環變形方法（ r _ = _ （ min ） _ （ max ） = - 1 ） ，系統研究了織構、熱處理狀態、氫對zr - 4合金低周疲勞性能的影響， zr - 4合金、 n18合金和n36合金的循環變形行為，並研究了摩擦應力、背應力隨循環周次、塑性應變幅的變化規律。結合疲勞亞結構和疲勞斷口的分析結果，深入探討了影響合金低周疲勞行為的作用機制。 -
With the typical on - axis fatigue tests to get the relative s - n curves of unidirectional laminates, executed at certain stress ratio, it is possible to predict the fatigue life of multidirectional laminates subjected to cyclic stresses of different stress ratios. this would tremendously reduce test costs for laminate structures
考慮了層壓板中單向層面內多軸應力和平均應力的影響，在已知單向板在確定應力比下受典型單軸循環應力的s - n曲線的基礎上，預測任意鋪疊次序層壓結構在不同應力比的循環載荷下的疲勞壽命。
