摘要

用边界元法分析了考虑剪切变形影响的穿孔板屈曲问题。几何非线性(GNL)效应包括旋转导数(曲率)和挠度导数。剪切变形在穿孔板屈曲中的重要性随着板厚的增加而显现，曲率的影响在大孔径情况下变得更大。

EFFECT OF CURVATURES IN THE BUCKLING ANALYSIS OF PERFORATED PLATES USING THE BOUNDARY ELEMENT METHOD

The buckling of perforated plates considering the effect of shear deformation is analyzed with the boundary element method. The geometrical non-linearity (GNL) effect included rotation derivatives (curvatures) as well as the deflection derivatives. The importance of the shear deformation in the buckling of perforated plates appeared with the increase of the plate thickness and the effect of curvatures becomes greater in large hole diameter cases.
