Stress at 10% deformation (σ10%), residual deformation (ɛr) and energy loss for cycles calculated from uniaxial cyclic tensile tests performed on bi-layered PU scaffolds. Values were calculated using the nominal dimensions of specimens.
| cycle | σ10% (MPa) | ɛr (%) | energy loss (%) |
|---|---|---|---|
| 1 | 0.79 | 2.5 | 45.6 |
| 2 | 0.77 | 2.7 | 20.7 |
| 3 | 0.76 | 2.9 | 18.1 |
| 4 | 0.75 | 3.0 | 16.8 |
| 5 | 0.75 | 3.1 | 16.1 |
