摘要
Abstract
Some problems on equivalent linearization of stresses calculated by FEA were studied, including the selection of the stress classification line and coordinate system, the linearization of transverse shear forces,the reason why membrane plus bending stress intensity is larger than total stress intensity, the treatment of the normal stress along thickness and the shear stress parallel to the mid - surface etc. Through analyzing some general phenomenon arising in several typical examples, a modified method for e-quivalent linearization of stresses was proposed.关键词
