| Outline of Final Research Achievements |
This research project was conducted by experts in Welding Mechanics, Fracture Mechanics and Experiment to establish a “Strategic Four Dimensional CAE Visualization System” which enables us to predict the quality and the performance of welded structures through their lifetime starting from their design and production. After three years research, (1) FE code capable to predict residual stress and distortion of large welded structures, (2) Advanced FE code for control and mitigation of welding residual stress and distortion, (3) FE code to predict crack propagation in large scale structures under the influence of welding residual stress are developed. Further, Codes (1)-(3) are integrated as a “Strategic Four Dimensional CAE Visualization System” and it is validated through experiments focused on fatigue crack growth in welded specimens.
