梁の3次元大変形の有限要素法解析 (第3報)

アーチの座屈解析と実験による検証

抄録

In Part 1 and Part 2, the authors presented a new finite element formulation for the analysis of large deformations of spatial beams, and demonstrated the accuracy and the efficiency of the proposed method by the numerical examples. In this paper, we analyze the post-buckling behavior of clamped circular arches subjected to a central concentrated load, and conduct experiments to verify the numerical results. The experimental data agree well with the numerical results, confirming the efficiency of the proposed method.
