Conclusions

  1. 1.

    The walls of the iliac and carotid arteries have pronounced mechanical anisotropy: The tissue strength in the direction perpendicular to the vessel axis is greater than in the parallel direction.

     
  2. 2.

    The carotid arterial tissue strength in the direction transverse to the vessel axis is greater than the iliac arterial tissue strength. The differences between the strength parameters in the longitudinal direction are insignificant.

     
  3. 3.

    With increasing age of the body, the strength of the carotid and iliac arterial tissues decreases in both the transverse and longitudinal directions, as indicated by the inverse correlation between σ1 and σ2 and age.

     
  4. 4.

    Change in the mechanical properties of vascular tissues occurs over periods in each of which the ultimate strength is approximated by a decreasing exponential function.

     
  5. 5.

    The strength decrement constants βn in the various periods of life are greater in the young and adult periods and significantly smaller in the geriatric period. A decrease in the rate of aging of arterial tissues is observed with increasing age.

     
  6. 6.

    The decrease in strength using the ℵ criterion characterizes the most rapid aging of the iliac arterial tissues relative to the carotid arterial tissues over the whole ontogenesis segment studied.
