解釋
反復張力-
While cyclic deformation experiment under constant strain control is performed in 400, the material shows the continuous hardening until cyclic invalidation. ( 3 ) back stress attained by kwl " s method is used to analyse the bauschinger effect during an incremental step cyclic test and cyclic deformation test under constant strain control, it is shown that back stress increases with increasing plastic strain and the numbers of cycle, and the back stress is uniform, regardless of tension or compression conditions. ( 4 ) as far as recrystallized zircaloy - 4 plate is concerned, the back stress in transverse direction is higher than that in rolling direction due to the higher schmid factor in rolling direction
對于再結晶狀態的zr一4合金板材試樣來說， t方向（橫向）試樣的背應力要高於r方向（軋制方向）的背應力，原因在於r方向的schmid因子高於t方向的schmid因子; 400下， zr一4合金的背應力要明顯低於室溫下的背應力;含氫200pg / g的zr一4合金的背應力大小與無滲氫的zr一4合金背應力相比，無明顯區別;固溶處理后， zr一4合金的背應力大小發生了變化，在較高塑性應變下，背應力均高於固溶處理前的背應力。 -
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。 -
Compared with those of as - sprayed ring, hardness and tension strength of area near processing face are increased by 45 % and 40 % respectively. friction mechanical performance of the ring is improved at large extent, and especially the wearing amount is merely 13 % of as - sprayed rings. after dual - direction cyclic pressing, the pore - closed state and the distributing of density and hardness are nearly identical in every part of ring. the friction mechanical property is close to that of single - direction - cyclic - press ring
靠近壓力加工面部位，硬度較沉積坯提高了45 % ，拉伸強度較沉積坯提高了40 % 。雙向楔壓后孔洞閉合、密度硬度分佈都比較均勻。單向楔壓后，用壓力加工面作為摩擦面， al - 20 % si / sicp復合材料的摩擦磨損性能得到大幅度提高，尤其磨損量為楔壓前的13 % 。 -

通過雙軸拉壓實驗來確定材料的切變鬆弛模量，單軸拉伸實驗來確定材料的體變鬆弛模量，對這兩種模量均採用分數階指數的形式來進行擬合，再用等應變幅循環歷史的實驗驗證了理論，得到了較好的結果。 -
Merely the fatigue strength in uniaxial tension or compression under constant - amplitude cyclic loading is given in the existing design code. the design result by using the fatigue strength in the code is apt to conservative under variable - amplitude or triaxial cyclic compression loadings, but sometimes apt to dangerous in uniaxial or triaxial tension - compression fatigue loadings
現行規范中，僅有混凝土單軸、等幅波動拉伸和抗壓強度指標，採用這些指標進行設計，會導致設計結果有時偏於保守，如變幅及多軸壓疲勞；而有時又偏於危險，如單軸及多軸波動拉-壓疲勞。 -
