EXPERIMENTAL INVESTIGATION ON LIMIT PRESSURE OF ORTHOGONALLY INTERSECTING CYLINDRICAL SHELLS WITH DIFFERENT DIAMETERS

    Graphical Abstract
    • Abstract
  • 内压下异径正交圆柱壳的极限承载能力受到普遍关注。本实验完成了ρ≈0.3,0.5,0.7,0.8四种开孔率的8个钢制模型实验研究。测量压力-应变曲线,按零曲率准则和双切线准则确定实验极限压力。结果和极限分析有限元上限格式解相当吻合。文中讨论了塑性流动大变形情况的应变测量技术问题。
