摘要
应用精确的锥壳屈曲分支方程，研究圆锥亮在环向分布剪切力作用下的扭转稳定性，通过分支点屈曲模态的构造和Galerkin变分法的运用，建立相应特征方程，求得铰支与夹支圆锥壳较为理想的全锥度环向剪切屈曲临界值。
This paper is concerned with the toraional stability analysis of circular conical shells under circumferential tangential loads.The exact buckling bifurcation equations for the circular conical shells are studied By choosing the buckling modes close to the bifurcation point and the use of Galerkin method the characteristic equations are derived. The critical buckling shear is computed for shells in any conicity . Both hinged and clamped end conditions are considered in the analysis.
