Figure 8
The bar chart presents percentage differences from Ogden 002, Reppel and Weinberg, for mu subscript 1, alpha subscript 1, mu subscript 2 and alpha subscript 2. The vertical axis ranges from minus 10 to 10 per cent. Nine conditions are compared: 9 newtons 1.6 millimetres 1 bar, 9 newtons 2 millimetres 2 bar, 9 newtons 2.4 millimetres 3 bar, 11 newtons 1.6 millimetres 1 bar, 11 newtons 2 millimetres 2 bar, 11 newtons 2.4 millimetres 3 bar, 13 newtons 1.6 millimetres 1 bar, 13 newtons 2 millimetres 2 bar and 13 newtons 2.4 millimetres 3 bar. Values for the four parameters extend both above and below zero, with several reaching approximately plus or minus 10 per cent.Variation of optimized material parameters in comparison with Ogden 002.
