Table 3. Anisotropic Compression Test Results of Vegetable Ivory (Jarina).
Direction of Indentation | Tests Density (g/cm3) | Elastic Modulus (GPa) | Max Strength (MPa) | Strain to fracture | Work to fracture (MPa) |
---|---|---|---|---|---|
Transverse plane | 1.20 ± 0.05 | 1.68 ± 0.7 | 158 ± 40 | 0.26 ± 0.06 | 25 ± 8 |
Radial Plane | 1.20 ± 0.05 | 1.34 ± 0.4 | 146 ± 50 | 0.29 ± 0.07 | 27 ± 10 |
The errors provided for vegetable ivory represent the 1.96 times the standard deviation.
