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 ...

Welding distortion is practically an expected feature in shipbuilding, with a few exceptions; when thick plates are used, for example. Nowadays, the trend is to use thinner plates in order to reduce weight, aiming to reduce ...

In order to achieve automation of the plate forming process by line heating, it is necessary to know in advance the deformation to be obtained under specific heating conditions. Currently, different methods exist to predict ...

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 ...

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 ...

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 ...

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 ...
