We study a nonlinear, unsteady, moving boundary, fluid-structure interaction (FSI) problem arising in modeling blood flow through elastic and viscoelastic arteries. The fluid flow, which is driven by the time-dependent pressure data, is governed by 2D incompressible Navier-Stokes equations, while the elastodynamics of the cylindrical wall is modeled by the 1D cylindrical Koiter shell model. Two...

Abstract We present a novel formulation for the immersed coupling of isogeometric analysis and peridynamics simulation fluid–structure interaction (FSI). focus on air-blast FSI address computational challenges methods in fracture fragmentation by developing weakly volume-coupled means simple penalty approach. show mathematical several numerical examples inelastic ductile brittle solids under bl...

With the diquark structure of Λc, we investigate the branching ratios of Λc → nπ and pπ. The results show that without considering the final state interaction (FSI), the branching ration of Λc → pπ is only of order 10−6 whereas taking into account the FSI effects, this ratio could reach 10−4 and is at the same order as Λc → nπ. Concrete values depend on phenomenological parameters adopted in th...

In this article, we investigate the movement and vibrations of a blade due to presence mast. When passes in front mast, sudden pressure spike induces blade. To study influence stiffness, two different structures were studied. We present our numerical schemes concerning resolution flow, behavior structure coupling systems. Then, validate methods against an experiment (Bahaj et al., 2007). third ...

We study a nonlinear, unsteady, moving boundary, fluid–structure interaction (FSI) problem in which the structure is composed of two layers: a thick layer, and a thin layer which serves as a fluid–structure interface with mass. The fluid flow, which is driven by the time-dependent dynamic pressure data, is modeled by the Navier–Stokes equations for an incompressible, viscous fluid, defined on a...

The main purpose of this study is to reproduce in silico the dynamics of a bileaflet mechanical heart valve (MHV; St Jude Hemodynamic Plus, 27mm characteristic size) by means of a fully implicit fluid-structure interaction (FSI) method, and experimentally validate the results using an ultrafast cinematographic technique. The computational model was constructed to realistically reproduce the bou...

The rapid development of computing software has facilitated multifarious research in integrated circuit (IC) packaging.

The deformation behavior of a pH-sensitive hydrogel micro-fluidic valve system is investigated using inhomogeneous gel deformation theory, in which the fluid-structure interaction (FSI) of the gel solid and fluid flow in the pipe is considered. We use a finite element method with a well adopted hydrogel constitutive equation, which is coded in commercial software, ABAQUS, to simulate the hydrog...
