Role of visco-elastic rheologies in the persistence of heterogeneous stress distributions in dynamic rupture models.

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer

Understanding how past ruptures will affect the propagation of the following ruptures is fundamental to a better comprehension of earthquake behavior. In that sense, numerical simulations provide a useful tool to study the dynamics of slip. In this study, ...

On the Estimation of Total Arterial Compliance from Aortic Pulse Wave Velocity

Nikolaos Stergiopoulos, Orestis Vardoulis

Total arterial compliance (C (T)) is a main determinant of cardiac afterload, left ventricular function and arterio-ventricular coupling. C (T) is physiologically more relevant than regional aortic stiffness. However, direct, in vivo, non-invasive, measure ...

A fluid mechanical view on Abdominal Aortic Aneurysms

François Gallaire

Abstract * Article Structure * Figures and Tables * References Abdominal aortic aneurysms are a dilatation of the aorta, localized preferentially above the bifurcation of the iliac arteries, which increases in time. Understanding their localization and g ...

Effect of flow diverter porosity on intraaneurysmal blood flow

Nikolaos Stergiopoulos, Mohamed Farhat, Philippe Reymond, Luca Augsburger, Edouard Fonck

Growth and rupture, the two events that dominate the evolution of an intracranial aneurysm, are both dependent on intraaneurysmal flow. Decrease of intraaneurysmal flow is considered an attractive alternative for treating intracranial aneurysms by minimall ...

Effect of an abdominal aortic aneurysm on wave reflection in the aorta

Nikolaos Stergiopoulos, Patrick Segers

Despite extensive attention to abdominal aortic aneurysm (AAA) in the biomedical engineering community, its effect on aortic hemodynamics and arterial wave reflection has not been addressed before. We used experimental and numerical methods, relying on a r ...

Structural strain energy function applied to the ageing of the human aorta

Nikolaos Stergiopoulos, Martin Zulliger

Stiffening of the aorta with progressing age leads to decrease of aortic compliance and thus to an increase of pulse pressure amplitude. Using a strain energy function (SEF) which takes into account the composition of the arterial wall, we have studied the ...

Conductance catheter-based assessment of arterial input impedance, arterial function, and ventricular-vascular interaction in mice

Nikolaos Stergiopoulos, Patrick Segers, Nico Westerhof

Global assessment of both cardiac and arterial function is important for a meaningful interpretation of pathophysiological changes in animal models of cardiovascular disease. We simultaneously acquired left ventricular (LV) and aortic pressure and LV volum ...

Total arterial inertance as the fourth element of the windkessel model

Nikolaos Stergiopoulos, Nico Westerhof

In earlier studies we found that the three-element windkessel, although an almost perfect load for isolated heart studies, does not lead to accurate estimates of total arterial compliance. To overcome this problem, we introduce an inertial term in parallel ...

Role of total arterial compliance and peripheral resistance in the determination of systolic and diastolic aortic pressure

Nikolaos Stergiopoulos, Nico Westerhof

The goal of the study was to define the major arterial parameters that determine aortic systolic (Ps) and diastolic (Pd) pressure in the dog. Measured aortic flows were used as input to the two-element windkessel model of the arterial system, with peripher ...
