CATASTROPHIC BEHAVIOR FOR STATIC BUCKLING OF ELASTIC ARCHES

摘要: 应用数学突变理论研究弹性两铰拱的静力屈曲，分析中考虑了拱的挠度变化、轴向压缩变形的影响，得到拱面内失稳的尖点突变模型和临界条件.

Abstract: In this paper, catastrophe theory is applied toinvestigate of the static buckling of elastic arches. The influences ofthe deflection change and axial deformation are considered. A cuspcatastrophic model and the critical condition for static buckling of arches areobtained.
