Numerical study of inherent deformation produced in thick plates through bending by line heating
In ship building, line-heating is widely employed as an effective method to form steel plate with complex 3-dimensional carved geometries. However the plate bending by line heating is strongly dependent on skills. To ...
Effect of phase transformation onset temperature on residual stress in welded thin steel plates
The effect of solid-state phase transformation at low temperature on residual stresses in butt welded ferritic thin steel plates has been examined employing a finite element (FE) code. An algorithm considering the solidstate ...
A numerical study of parameters governing an inherent deformation database of plates formed by line heating
As an overall strategy to improve the accuracy of the forming process, the authors pay attention to those factors which may influence the inherent deformation of plates formed by line heating. In order to identify those ...
Analysis and prediction of welding distortion in complex structures using elastic finite element method
The Elastic Finite Element Method based on the inherent strain theory is used to predict the welding distortion of ship structures. In addition, a method to predict welding distortion of complex structures by using elastic ...
Influential factors affecting inherent deformation during plate forming by line hating (Report 1) - the effect of plate size and edge effect
The authors aim to propose an accurate and practical method to predict the deformation of actual plates of large size such as those used in shipbuilding. This method is to be used to improve the accuracy of an automatic ...
