A comparison of modelling techniques for computing wall stress in abdominal aortic aneurysms
modelling techniques wall stress abdominal aortic aneurysms
2010/2/25
The results here show that using more realistic parameters affect resulting wall stress. The use of simplified computational modelling methods can lead to inaccurate stress distributions. Care should ...
Fluid structure interaction of patient specific abdominal aortic aneurysms: a comparison with solid stress models
Fluid structure interaction patient specific abdominal aortic aneurysms solid stress models
2010/2/26
Abdominal aortic aneurysm (AAA) is a dilatation of the aortic wall, which can rupture, if left untreated. Previous work has shown that, maximum diameter is not a reliable determinant of AAA rupture. H...
Analysis and computer program for rupture-risk prediction of abdominal aortic aneurysms
computer program rupture-risk prediction abdominal aortic aneurysms
2010/2/26
As part of computational AAA-risk assessment and medical management, a patient-specific severity parameter 0 < SP(t) < 1.0 has been developed. The time-dependent, normalized SP(t) depends on eight bio...
Fluid-structure interaction in abdominal aortic aneurysms: effects of asymmetry and wall thickness
Fluid-structure interaction abdominal aortic aneurysms
2010/2/26
Both wall thickness and geometry asymmetry affect the stress exhibited by a virtual AAA. Our results suggest that an asymmetric AAA with regional variations in wall thickness would be exposed to highe...
