Description
Summary:This article introduces the concept and formulation of the boundary element method, and its application to rolling technology with special respect to the flatness problem in flat rolling. The possibility of utilization of the boundary element method in the inverse analysis is also discussed, and the residual stress analysis in the rolled sheet and estimation of the rolling pressure distribution along the width direction are presented as numerical examples. With use of the boundary element methods the effect of the ratio of sheet width to barrel length is discussed. With increase in the ratio, the crown of the rolled sheet decreases. The effect of the roll bending force on the tension distribution in the rolled sheet is also simulated.
