Key result
Compared with a purely elastic response, the viscoelastic property of arteries reduces the magnitudes and temporal variations of circumferential stress and strain, as well as radial wall movement.
Viscoelastic properties of arteries reduce dynamic stresses and strains, which may protect blood vessels from fatigue failure over millions of cardiac cycles.

May inform arterial fatigue models in simulations; extends elastic theory but leaves human translation open.
Zhang et al. (2007) studied Blood vessel mechanics. Viscoelastic model vs. Elastic model was evaluated on Magnitudes and temporal variations of circumferential stress and strain, and radial wall movement. Compared with a purely elastic response, the viscoelastic property of arteries reduces the magnitudes and temporal variations of circumferential stress and strain, as well as radial wall movement.
