  1. Through the analysis we found that the effect will become more obviously with the increase of thickness or width of superstratum and the decrease of the coefficient of foundation bed ; ( 3 ) anisotropy and nonlinear elastic f. e. m. model has been established and the effect of stress dispersion in compound two - layer foundation was analyzed on the base of the model. from the analysis we can conclude that the coefficient of subsidiary stress dispersion will amplify with the increase of thickness or width or stiffness of back - up coat ; ( 4 ) the formula which can be used in conventional calculation has been deduced for calculating the coefficient of subsidiary stress dispersion and it also has been affirmed to be reasonable through the checking calculation ; the whole theory of compound two - layer foundation has been brought forward in this paper and it ' ll enrich the theory of composite foundation

    針對以上問題本文做了以下一些工作並得到若干結論： （ 1 ）提出了「復合雙層地基」的概念，並通過工程實例證明此概念的提出有其合理性和必要性； （ 2 ）用彈性地基梁理論證實了復合雙層地基確有應力擴散效應，且擴散效應隨上覆硬層厚度、剛度的增加而增大，隨下臥層基床系數的增大而減小； （ 3 ）建立了非線彈性、各向異性有限元模型，並以此為基礎分析了復合雙層地基的應力擴散效應，得到附加應力系數隨加固層厚度、寬度、剛度的增加而增大的結論； （ 4 ）推導了可用於常規計算的復合雙層地基應力擴散系數公式，並代入工程實例進行了驗證。
  2. 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。
  3. So it is very important to understand the cyclic deformation behavior of zircaloy - 4. in this paper, bauschinger effect of zircaloy - 4 with different metallurgical state at room temperature and 400 ? is investigated in an incremental step test and cyclic deformation test under constant strain control. bauschinger effect during cyclic deformation is described by using back stress, which is mainly responsible for bauschinger effect ; back stress is attained by using kwl " s method

    本文採用單試樣逐級加載循環變形和恆應變幅循環變形試驗，研究了不同冶金狀態、溫度、氫以及固溶處理下的zr - 4合金的bauschinger效應現象；種種結果表明，影響bauschinger效應的主要因素是背應力；本文正是從背應力的角度來分析各種狀態下zr - 4合金的bauschinger效應現象；背應力的計算主要通過使用kwl方法而獲得。
