Sažetak
A framework for coupling finite element growth and remodeling (G&R) analysis of abdominal aortic aneurysm (AAA) with hemodynamics analysis is presented. Majority of AAAs harbor intraluminal thrombi (ILTs) which have biochemomehanical influence on aortic wall, and therefore active role in G&R of AAA. Based on time averaged wall shear stress from hemodynamics analysis, layers of ILT are added on luminal surface of AAA model. Analyses are loosely coupled and run in a time loop where G&R analysis has longer time scale (i.e. months) while hemodynamics analysis has shorter time scale (i.e. seconds).
