Results from a severely stenosed plaque (modified from Plaque #2) demonstrate that plaque morphology and pressure drop conditions have considerable effects on flow and wall stress/strain behaviors. (a) Modified plaque with stenosis severity 70% by diameter; (b) Stress-P₁ at the tracking point (throat of the plaque) from the non-Newtonian FSI model is about 145% higher than that from the wall-only model; (c) MSS at the tracking point from the flow-only model is about 40% higher than that from the non-Newtonian FSI model. MSS from Newtonian FSI model almost overlaps the non-Newtonian curve.
