Prediction of Welding Distortion During the Assembly Process of Thin Plate Structures (1st Report)—Prediction of Welding Distortion Considering Gap and Misalignment—
Interface Element Welding Distortion Welding Sequence Gap Misalignment
2009/5/19
The welding distortion of a plate structure during the assembly process is influenced not only by the local shrinkage due to the welding thermal cycle but also by the root gap and the misalignment. Th...
New Long-term Prediction of Ship Responses Considering Critical Standard Deviation
Long-term Prediction Critical Standard Deviation Ship Response Monitor Data Exceeding Probability Critical Value Critical Probability
2009/5/12
The conventional long-term prediction of responses estimates a higher value than that of real value, because it does not consider a ship operation and assumes the linearity between significant wave he...
