Abstract
The finite element method is a powerful tool for predicting welding residual stresses and distortions. However, the phenomena in welding are three-dimensional in their nature. Generally, the three-dimensional thermal-elastic-plastic FE analysis requires very long computational time and large memory size. To overcome this problem, the idea of a fractal multi-grid method is proposed. Its potential capability is demonstrated through application to very simple mechanical and thermal problems.
