ABSTRACT Reported in this paper is a cutting‐edge computational investigation into the influence of geometric characteristics on abdominal aortic aneurysm (AAA) rupture risk, beyond traditional measure maximum diameter. A Comprehensive fluid–structure interaction (FSI) analysis was employed to assess risk factors range patient scenarios, with use three‐dimensional (3D) AAA models reconstructed from patient‐specific data and finite element method. Wall shear stress (WSS), its derivatives such as time‐averaged WSS (TAWSS), oscillatory index (OSI), relative residence time (RRT) transverse (transWSS) offer insights force dynamics acting wall. Emphasis placed these WSS‐based metrics seven key indices. By correlating discrepancies biomechanical phenomena, study highlights novel profound impact geometry prediction. This demonstrates necessity multidimensional assessment approach, future efforts should complement findings experimental validations for an applicable approach clinical use.
