Table 2 Details of sample types and test settings of respective biomechnical evaluations
Test | Tensile | Compression | 3 point bend |
|---|---|---|---|
Sample type | Dumbell section (50 mm length) excised as indicated (Supplementary Figure 10) | Samples of approx 15 mm in height | Adult trachea samples 84 × 25 × 23 mm |
Test Conditions | Cross head speed −20 mm/min Guage length-20 mm | Crosshead speed 10 mm/min | Crosshead speed-10 mm/min |
Test description summary | Tensile tests were carried out essentially in accordance with ISO37:2011 | Samples were compressed to 50% of their original width. Each sample was pre-conditioned (at a rate of 15 m m/s) | Trachea samples were subjected to three point bend test and the force required to move at a speed of 10 mm/min was recorded |
