In this contribution, the tensile behavior of an isolated corrugated sheet is analyzed. A simple analytical model is developed to describe the unbending of the corrugation and the stretching of the sheet as a function of the initial geometric and material parameters. The model predictions are in good agreement with experimental observations for corrugated sheets of IF steel.
