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 ...
Numerical analysis of the straightening process of thin plate structures by elastic FEM based on the inherent strain method
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 ...
Development of a neural network model to predict distortion during the metal forming process by line heating
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 ...
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 ...
