The New Effective Methodology for Prediction and Optimization of Distortion of Large Welded Structures

Abstract:

This paper deals with the new numerical methodology for prediction and optimization distortion of large welded structures. The methodology is presented on the example of fusion vacuum vessel of ITER which will be manufactured by welding. All necessary steps of methodology have been verified and now the methodology is ready for practical application. Application of our methodology leads to improve of knowledge about complex behavior and save time and budget.
