Figure 7
Stress–strain plots (loading and unloading) for two samples of an adventitia tested in the circumferential (C) and in the longitudinal (L) directions. Three ranges of the stress–strain plots are indicated: toe (up to A), heel (ranging between A and B) and lock (larger than B). AC, BC and AL, BL give the ranges for the circumferential and the longitudinal directions, respectively. |
