中文拼音 [jìngxiànglāshēnbiànxíng]
徑向拉伸變形
英文
radial draw deformation-
Considering different soil spring models for vertical fault movement and horizontal fault movement, two damage cases of pe pipeline in ji - ji earthquake have also been simulated. the large deformation of a buried pipeline under fault movement is investigated in the 4th chapter. to examine the inelastic behavior of buried pipelines, the parametric studies on pipe material property, diameter ( d ), diameter - to - thickness ratio ( d / t ), crossing angle ( ), as well as soil stiffness, have been conducted using a shell - spring fem method
對於0 p三90 」的情況，當斷層位移相對管徑還不是很大時（管子內的彎曲應變與軸向拉伸應變相差不大的情況） ，斷層附近管子變形形式與梁相似；當斷層位移相對管徑很大時（管子以軸向拉伸應變為主的情況） ，斷層附近的管子軸線變形為一圓弧，管子表現得像一條沒有彎曲剛度的索。With the different loading ratio of parallel to axis and normal to axis direction, damage defects will occur bulking problem. by varying the degree of material anisotropy relative to the loading axis such as poisson ' s ratio and shear modulus, crack growth bulking strain value parallel to or normal to the loading axis is different. the parameters controlling the growth or arrest of the delamination damage are identified as the geometry and the depth of defects and radius of cylindrical etc. at last, it was investigated that the delamination damage is often induced by the tip of matrix damage under higher stress
研究結果表明:殼體筒段受軸向拉伸和內壓載荷作用時，軸向和環向載荷的比率不同，母層和子層可能發生拉伸屈曲，也可能發生收縮屈曲，或者同時發生拉伸和壓縮屈曲;母層與子層各向異性存在差異，即泊松比與剪切模量不匹配時，將使子層板的邊界上承受壓縮和剪切作用，當分層達到臨界狀態則發生屈曲，當母層與子層的各向異性差異越大，則發生分層屈曲的可能性越大;分層損傷的屈曲應變值與子層自身的彈性模量、分層子層的形狀、厚度以及圓柱半徑等因素有關。Then mechanical experiments were carried out to measure the longitudinal tensile strength and radial supportive strength. based on the testing results, the different deformation functions of the tubular fabric were obtained and we conclude that the strength indexes vary directly as the material diameter and the arrangement of the pp and pgla has a prominent influence to the radial supportive strength of the woven artificial trachea. in addition, the degradation property of the tracheal prosthesis was investigated and this provides another important foundation for the fabrication technology of the artificial trachea
在試驗測試部分，本課題對試樣的拉伸性能和徑向強度進行了測定，根據試驗的結果深入研究了每種管道織物在測試過程中的不同變形作用，也得到了不同的編織工藝參數對人工氣管力學性能的不同影響:原料的細度的變粗可增大人工氣管各力學強度指標;機織組織管道織物中兩種原料的排列方式對人工氣管的拉伸性能並無明顯影響而對其徑向強度影響顯著，其中以「 1隔1 」和「 3隔3 」的排列方式較佳。
