Results from this study provide important basis for buckling experiments of thin shell structures 本文成果與方法為薄殼結(jié)構(gòu)屈曲試驗(yàn)奠定了基礎(chǔ)。
As regards to the spheric thin shell structure under external hydro static pressure , basing on flat - plate theory and by using basic von karman equations for large deflection , the equilibrium problem of axisymmetric bending of the spheric shell under uniform external pressure is simplified to an equilibrium problem of bending of elastic basic flat - plate and further converted into an equilibrium problem of beam on elastic fundation taking into consideration of the deformation characteristics 對(duì)球形薄殼結(jié)構(gòu)隨靜水外壓的情況,應(yīng)用平板理論中的vonkarman大撓度基本方程,將球形薄殼在均勻外壓下的軸對(duì)稱彎曲平衡問題簡(jiǎn)化為彈性基礎(chǔ)平板的彎曲平衡問題,進(jìn)而再根據(jù)變形特點(diǎn)將其轉(zhuǎn)化為彈性基礎(chǔ)梁的復(fù)雜彎曲平衡問題。
