| Abstract: | A fractal model for cavity damage and fracture of materials during superplastic deformation is proposed in this paper. The formula which shows the effect of gauge dimensions and grain size on total superplastic elongation was inferred. The formula shows that the finer the grain size, the larger the elongation of specimen and a larger elongation can be obtained by increasing the gauge width and thickness or by decreasing the gauge length of specimen under the same deformation condition. The prediction of the new formula is consistent with most experimental results observed up to now. |
