Figure 6: ANN inverse training results for the highly sensitive material parameter (yield strength) from the 500 FEM testing data. Figures 6(a) and 6(b) show the training case in which the other 6 material parameters have also been used. Figures 6(c) and 6(d) illustrate the case in which was trained alone. However, the whole normalization of 70 strains (1 group) over 4,500 datasets generates Figures 6(a) and 6(c), whereas Figures 6(b) and 6(d) come from the individual normalization of the 70 strain input data (70 groups).
