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 establish a plate bending method which is less dependent on skill, the deformation...

Descrição
Resumo: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 establish a plate bending method which is less dependent on skill, the deformation produced by single or multilayer heating is necessary. In this report, the distribution characteristic of inherent deformation produced in thick plate by single pass and two-pass overlap heating is discussed. In this report, the three-dimensional FEM using the ISM method is employed. Using the deformation computed by ISM, the inherent deformation produced in thick plate by line heating is estimated through inverse analysis.
