摘要: 采用修正的Morly方程,以ρ0,Y/R为小参数,对圆柱壳大开孔的边界条件进行渐近展开,得到了可适用于ρ0≤0.7,情况下的薄壳理论解。Abstract: The analytical solution for cylindracal shells with ρ0≤0.7,r_0,R radii of hole and shell,respectively; T thickness of shell)are presented inthis paper by solving the modified Morley’s equation. The accurate boundary conditions atthe hole edge are asymptoticly expanded in powers of ρ0 and T/R.
