On the Deformation of Plate at the Process of Corrugation

Abstract

The deformation of plate produced at the process of corrugation makes it difficult to prepare smooth butts for a preassembly consisting of corrugated Plates. It was confirmed experimentally and theoretically that the deformation of Plate was caused by residual stresses produced during gas cutting of Plate edes. Low temperature stress releasing was conducted in various ways to reduce the residual stresses before corrugation. The results of the experiments show that the low temperature stress releasing is quite effective to reduce the residual stresses and, eventually, the deformation of the plate.
