Prediction of steel plate deformation due to triangle heating using the inherent strain method [PDF]

Journal of Marine Science and Technology, 2005
In a shipyard, line heating and triangle heating are two major processes carried out by skilled workers to form curved plates in various shapes under various heating conditions. There have been many studies on line heating, but triangle heating has rarely been studied owing to its complicated heating process with irregular multiheating paths and highly

Development of Thermal Distortion Analysis Method Based on Inherent Strain for TMCP Steels

Journal of the Korean Welding and Joining Society, 2008
As ships become to be larger than ever, the thicker plate and the higher tensile steel plate are used in naval shipyard. Though special chemical composition is needed for high-tensile steels, recent high-tensile steels are made by the TMCP(Thermo-Mechanical control process) skill.

Welding Deformation Analysis of Plates Using the Inherent Strain-based Equivalent Load Method [PDF]

Journal of the Korean Welding and Joining Society, 2010
IIn this study, used is the equivalent loading method based on the inherent strain to predict the welding deformation of panel members. Equivalent loads are computed from the inherent strain distribution around weld line, and then applied for the linear finite element analysis. Thermal deformation of panel members can be, of course, carried out through
