Impact of poroelasticity of intraluminal thrombus on wall stress of abdominal aortic aneurysms

Table 2 Influence of material model and pressure boundary condition (BC) on stress in AAA

Peak Wall Stress (PWS) (i.e. peak von Mises stress) and peak 1^st principal Cauchy stress in the AAA wall predicted by different Finite Element (FE) models. FE models either neglect the ILT or consider it using a single-phase or a poroelastic description. The pressure BC considers either a constant blood pressure (constant) or a time and space-dependent blood pressure wave (Pressure wave). Inertia effects are neglected in all cases.
