An intraluminal thrombus (ILT) forms along the inner layer of the aorta in 75% of abdominal aortic aneurysms (AAAs) [1] and can often times cover a large surface area of the AAA wall. Mechanical modeling of the ILT is essential in many AAA studies. For example, inclusion of the ILT in rupture risk models significantly affects the estimated stress acting on the aneurysmal wall [2]. In addition, using ILT mechanical properties to model fluid flow through the ILT is critical to developing an intraluminal drug delivery treatment of AAAs to ensure the drug reaches the aneurysmal wall.
