	abstract = {We present a preliminary study on aneurysm wall vibrations associated with turbulent-like hemodynamics in intracranial vascular sections. The specificity of our numerical model is to explore the fluid/structure coupling of the arterial flow and the wall mechanics to relatively high frequencies (100-500 Hz). Despite the computational cost of the couple FSI problem and its direct impact on the resolutions of the model presented here, our findings highlight an important mechanical interplay resulting in a complex, but characteristic, deformation of the arterial wall. We hope to stimulate discussions and further work towards this physiological process, which can potentially have important implications for cell signaling mechanisms.},

	title = {Can turbulent-like flow cause high frequency vibrations of intracranial aneurysm walls ?},

	address = {Biomechanics in Vascular Biology and Cardiovascular Disease (14th international symposium), London, United Kingdom},
	abstract = {The presence of wall vibrations of relatively high frequencies (several hundreds of Hz) on the top of intracranial aneurysms have been reported in the 70{\textquoteright}s from open brain surgery measurements [1]. Later study [2], based on non-invasive recordings, provided additional evidences for charateristic high frequencie intracranial blood flow sounds associated with the presence of aneurysms. It is only recently that computational and experimental in-vitro studies modelled turbulent-like blood flow environments within intracranial vasculature, with characteristic fluctuations in the order of 100-300 Hz ([3, 4]). However, the link between unstable blood flow and arterial wall vibrations within intracranial aneurysms still remains speculative and is the focus of the present work.},

	abstract = {Strain localization is ubiquitous in geodynamics and occurs at all scales within the lithosphere. How the lithosphere accommodates deformation controls, for example, the structure of orogenic belts and the architecture of rifted margins. Understanding and predicting strain localization is therefore of major importance in geodynamics. While the deeper parts of the lithosphere effectively deform in a viscous manner, shallower levels are characterized by an elastoplastic rheological behavior. Herein we propose a fast and accurate way of solving problems that involve elastoplastic deformations based on the consistent linearization of the time-discretized elastoplastic relation and the finite difference method. The models currently account for the pressure-insensitive Von Mises and the pressure-dependent Drucker-Prager yield criteria. Consistent linearization allows for resolving strain localization at kilometer scale while providing optimal, that is, quadratic convergence of the force residual. We have validated our approach by a qualitative and quantitative comparison with results obtained using an independent code based on the finite element method. We also provide a consistent linearization for a viscoelastoplastic framework, and we demonstrate its ability to deliver exact partitioning between the viscous, the elastic, and the plastic strain components. The results of the study are fully reproducible, and the codes are available as a subset of M2Di MATLAB routines.},
