摘要: 
The main purpose of this paper is to explore buckling deformation patterns and buckling stress of the thin cylindrical shell subjected to axial force.Using three-dimensional elastic stability variational principle to derive three-dimensional finite element model of elastic stability analysis.The analysis shows that buckling stress is easy to be influenced by the opening size of thin cylindrical shell.The upper limit value of buckling stresses of thin cylindrical shell are lower than which has no opening hole.The main parameter to the buckling stress is radius and thickness ratio of thin cylindrical shell.

本論文主要目的在探討開孔薄殼圓柱於軸壓作用下之挫曲變形型態及挫屈應力。利用三維彈性穩定變分式推導彈性穩定三維有限元素分析模式,分析薄殼圓柱在有矩形開孔且其邊界條件在兩端為固定情況下之不同長度L、半徑R及厚度t與不同開孔角度、高度對承受軸向應力作用下之挫屈應力及挫屈模態影響。分析顯示挫屈應力易受到薄殼圓柱之開孔大小所影響,而開孔薄殼之挫屈應力上限值都低於無開孔薄殼圓柱之挫屈應力。對於有開孔之薄殼圓柱之挫屈應力值,最大影響參數主要為薄殼圓柱之半徑與厚度比。
