The article exposes robust finite element solutions for coupling flows in both purely fluid region, ruled by Stokes equations, and a porous region of low permeability (down to 10−15 m2) governed Darcy's equations. Relying on stabilised FE formulations, two different numerical strategies are investigated Stokes–Darcy flows: decoupled strategy, based the use matching meshes spaces discretising coupled system; unified or monolithic consisting defining one single mesh computational domain,...
When fatigue tests are carried out using a shaker, dynamic phenomena often appear and lead to non-linear behaviour in the experiment. In this paper, response of specimen is studied order evaluate impact on results. The experiment consists notched beam fixed armature an electro-dynamic shaker. transfer function between center tip obtained with swept sine near first resonance frequency specimen. drive constant acceleration amplitude. An evolution observed when modified: decreases damping...
Reducing the noise level in acoustic cavities is important problem when treating inflight conditions of commercial planes or boats. Shape optimization cavity that will take into account geometrical and material uncertainties, arising during manufacturing process, presented this paper. The controlled by minimizing energy density cavity, obtained through an method called Simplified Energy Method. Such formulation based on our previous published work where transformation function mapping 3D...
In this paper, a comparison between six finite element models of representative wing structural component performed in the context Optimised Design for Inspection (ODIN) project European Cooperation Science and Technology (COST) is presented. Six partners from different countries involved received drawing structure, material properties, loading boundary conditions. Each partner, based on their background experience numerical analyses, developed model with levels details accuracy blind...
Modeling of acoustic propagation in a duct with absorbing treatment is considered. The surface impedance the sought form rational fraction. numerical model based on resolution linearized Euler equations by finite difference time domain for calculation under grazing flow. Sensitivity analysis considered performed. uncertainty physical parameters taken into account to determine most influential input parameters. robustness solution vis-a-vis changes flow characteristics and medium studied.
This paper deals with shape optimization issues under vibroacoustic criteria. The aim of the conducted research is to minimize energy density in cavity by changing its geometry parameters. obtained through an method called simplified (MES). based on a transformation function mapping 3D surface 2D domain. process directly relies this and thus avoids remeshing geometry. proposed allows describe Bezier, Bspline NURBS parametrization. To illustrate method, we simple acoustic cavity.
The problem of the vulnerability structures facing explosions came to front line scientific scene in last decades. Uncertainty environmental conditions and material properties have be taken into account. corresponding numerical models are very complex depend on numerous parameters. Consequently, such cursed with issues which limit their use for real applications. Most existing approaches based a deterministic point view, not able represent extreme sensitivity model towards uncertain That is...
At present, the Finite Element Analysis (FEA) method is indispensable in field of simulation technology, as this kind numerical analysis can help engineers to predict results, whic hare often difficult obtain from experimental tests. However, problem that during mesh generation process FEA, it required spend a long time. It estimated about 80 percent time are devoted some fields, such automotive or shipbuilding industries. On other hand, imperfections models lead inaccurate problems. Inthis...
