| Research Abstract |
Thermal fabrication processes such as plasma-cutting, gas-cutting, arc-welding, laser-welding, or straightening induce thermal and residual distortion. Improvement of fabrication accuracy strongly depends on these distortions, therefore precise predicting and controlling method of thermal and residual distortions must be one of the important technique for ship-building. Hybrid method by using "thermal process physics" and "thermal process mechanics" has been developed in this research in order to effectively improve fabrication accuracy during thermal fabrication process. Furthermore, multi-scale linkage among "microscopic process physics", "macroscopic thermal process mechanics," and "megascopic structural mechanics" considering assembling order with a simplification by using inherent strain methodology achieves the condition of higher accuracy and robustness in welded structures.
