Key result
In a computational model of a 45% stenosed vessel, wall compliance slightly lowered wall shear stress by less than 7.2% compared to a rigid model, but did not qualitatively change flow behaviors.
Computational modeling of a mildly stenosed tube demonstrated that wall compliance had small effects on flow and solid behaviors, slightly reducing wall shear stress compared to rigid models.

Minor compliance effects in mild-stenosis CFD models; leaves open whether rigid walls suffice for clinical simulations.
Lee et al. (2002) studied Stenosed vessel. Compliant wall model vs. Rigid wall model was evaluated on Fluid flow and wall motion (velocity profiles, wall shear stress, intramural strain and stress). In a computational model of a 45% stenosed vessel, wall compliance slightly lowered wall shear stress by less than 7.2% compared to a rigid model, but did not qualitatively change flow behaviors.
