Deformation and Strength of a Corrugated Plate

Abstract

The problem of a corrugated plate under a uniformly distributed load is studied in this paper, and the deformations and stresses produced are discussed. The cross section of the corrugated plate is considered as a combination of two cylindrical shells with the same radius, and using the differential equations of thin shell theory introduced by Dr. Mizoguchi, an exact solution is obtained, and the results are compared with the experimental ones. In the numerical calculation, we took into account various values of the length of shells, and two forms of the cross section. The results show that the deformations and stresses have considerably various features according to the length of the shell and the forms of the cross section. For instance, in the case of long shells, we can say the results are similar to those of the elementary beam theory, but, as the length of shells turns out to be smaller, the results become complicated gradually.
