Deformation Prediction of Plate Line Rolling Forming Based on Inherent Strain Method [PDF]

Mathematical Problems in Engineering, 2017
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.

Development of a Practical Straightening Simulation for Welded Structures Using Inherent Strain Method

KnE Engineering, 2018
Welding is the most widely used assembly method available to industries in the construction of metal structures, ships, and offshore platforms. However, this method always produces a certain amount of distortion that will not only degrade the performance but also increase the building cost of the structure, and it should be straightened.
