“Deformation Prediction of Plate Line Rolling Forming Based on Inherent Strain Method”, Mathematical Problems in Engineering, Volume 2017, Article ID 7417142, 8 pages, https://doi.org/10.1155/2017/7417142
ABSTRACT: Inherent strain method has been widely used as a forecasting and computing method for welding deformation of large complicated structures and further applied to the research of line heating forming. Mechanical forming is a common ship-hull plate forming method, for which deformation prediction still depends mainly on elastoplastic finite element method. This paper researched the application of inherent strain method to plate line rolling forming, a common mechanical forming method, and then compared the results of inherent strain method and elastoplastic finite element method, proving the applicability of inherent strain method, providing a method for fast, accurate forecasting of distortion in plate line rolling and formation of automation equipment.
