Figure 9. Effective stress distributions versus normalized wall thickness for the idealized AAA model with thrombus.

Simulations were performed assuming a wall/thrombus material property ratio (MPR) of 4, 6.7 and 10.25, in the reference, conventional and linear models. In all cases, an internal pressure of 0.016 N/mm² (120 mmHg) was applied. Ref: reference model, Conv: conventional model.
