波纹壳（板）的分析是基于这样的假设，即它们可以作为均匀厚度的等效正交各向异性薄壳进行分析。对文献中给出的正交各向异性薄壳等效刚度的解析表达式进行了评述。恒应变状态下波纹板的有限元分析结果揭示了当今使用的一些经典表达式的不足之处。这些等效正交各向异性性质的改进与新的表达式的推导。此外，表达式的局部应力集中的波纹的脊处开发。
The analysis of corrugated shells (plates) is based on the assumption that they can be analyzed as thin, equivalent orthotropic shells of uniform thickness. The analytical expressions for the equivalent rigidities of orthotropic thin shells given in the literature are reviewed. The results of a finite element analysis of a corrugated sheet subjected to constant strain states reveals an inadequacy in some of the classical expressions in use today. These equivalent orthotropic properties are improved with the derivation of new expressions. In addition, expressions for the localized stress concentrations developed at the ridges of the corrugations are derived.
