Key result
Elastic lamellae deform equally across the media, suggesting it acts mechanically as a homogeneous material.
Why the study?
Most computations of arterial mechanics treat the wall as mechanically homogeneous, but there are no data to support or refute this assumption.
This study demonstrates that despite histological heterogeneity, the arterial media acts mechanically as a homogeneous material.

Supports homogeneous arterial media modeling in biomechanics; leaves open translation to human hypertension.
Philip B. Dobrin (1999) studied Arterial mechanics. Normal cylindrical configuration versus inverted cylinder was evaluated on Deformation of 4 elastic lamellae across the thickness of the media. Extensibilities and circumferential retractions of the elastic lamellae were equal at all anatomic locations across the media, suggesting the media acts mechanically as a homogeneous material.
