Temperature | G′ (MPa) | E-Modulus (MPa) | E/G′ (−) | σ10% (MPa) | σy (MPa) | ɛy (%) | σb (MPa) | ɛb (%) | σ atrue (MPa) |
---|---|---|---|---|---|---|---|---|---|
20 °C | 20 | 53 | 2.7 | 4.5 | 8.7 | 49 | 29 | 480 | 165 |
50 °C | 20 | 59 | 3.0 | 3.8 | 7.2 | 42 | 22 | 550 | 143 |
80 °C | 18 | 56 | 3.1 | 3.4 | 5.8 | 37 | 17 | 490 | 98 |
110 °C | 16 | 53 | 3.3 | 2.9 | 4.7 | 33 | 12 | 400 | 61 |
a σtrue was obtained by multiplying σbreak with the straining factor (=1 + (ɛbreak/100))
