Table 4.

Peak wall stress (N/cm²) for two patient-specific AAA models exposed to patient-specific diastolic and average systolic pressures compared to average diastolic and systolic pressures. Stresses are shown for the initial CT image-based geometry ($S_{\text{ib}}$) and the unloaded geometry ($S_{\text{ug}}$). The percentage differences are calculated with respect to the average diastolic pressure loading condition.
