Welding Deformation of Large-Complex Ship Subsection
摘要
Abstract
For prediction on welding deformation of large and complex ship subsection, thermal elastic-plastic method was employed to obtain inherent strain from simulating welding deformation of typical structures. And inherent strain method was adopted to simulate the welding deformation of ship subsection. The results were compared and verified with the actual measurement. The conclusion indicates that using inherent strain method to simulate the welding deformation of large and complex ship subsection is feasible, and welding deformation of ship subsection exhibits phenomena of completely stretching out, where deformations at the edge of broadside are the largest.关键词
