Rotating machinery such as centrifugal fans is often exposed to unsteady aerodynamic loads that can induce fatigue damage during prolonged industrial operation. This study investigates the fatigue life of a centrifugal fan (FN280) used in a cement plant through a one-way fluid–st
Evaluation of Damage Index of Eccentrically-Braced Frames according to Link Beam’s Length with Soil-Structure Interaction Effects
Due to features such as ductility and stiffness, the eccentrically-braced frames(EBF) have a good performance against seismic loads and have been considered by designers. Previous studies indicate that the soil underlying the structures affects their seismic behavior. In the case
Investigation of Fluid-structure Interaction by Explicit Central Finite Difference Methods
Fluid-structure interaction (FSI) occurs when the dynamic water hammer forces; cause vibrations in the pipe wall. FSI in pipe systems due to Poisson and junction coupling has been the center of attention in recent years. It causes fluctuations in pressure heads and vibrations in
Fluid-Structure Interaction of Vibrating Composite Piezoelectric Plates Using Exponential Shear Deformation Theory
In this article fluid-structure interaction of vibrating composite piezoelectric plates is investigated. Since the plate is assumed to be moderately thick, rotary inertia effects and transverse shear deformation effects are deliberated by applying exponential shear deformation th
Effects of the Soil-Foundation-Structure Interaction on the Component Demand Modifier Factor of Concrete Gravity Beams based on ASCE 41-06 Standard
The aim of the present paper is to evaluate the influence of the Soil- Foundation- Structure Interaction (SFSI) effects on the component demand modifier factor of concrete gravity beams based on ASCE 41-06 standard. To this end, the beam on the nonlinear Winkler foundation approa
Presenting a Modified SPH Algorithm for Numerical Studies of Fluid-Structure Interaction Problems
A modified Smoothed Particle Hydrodynamics (SPH) method is proposed for fluid-structure interaction (FSI) problems especially, in cases which FSI is combined with solid-rigid contacts. In current work, the modification of the utilized SPH concerns on removing the artificial visco

study of dynamic infinite element used for soil structure interaction
starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed spa
Dynamic Response Analysis of Tilting Pad Journal Bearing Considering Fluid-Structure Interaction
The transient hydrodynamic lubrication model of tilting pad journal bearings (TPJBs) was established by the computational fluid dynamics (CFD) method and the self-developed dynamic grid program. The fluid-structure interaction between the flow field and the rotor motion, the pads
Effect of Fluid-Structure Interaction on Noise Generation in MAV with Fixed and Flapping Membrane Wing
An experimental study on the effect of fluid-structure interaction on noise generation in Micro Air Vehicle (MAV) with fixed and flapping membrane Tipula sp. wing is investigated. The acoustic performance of the fixed and flapping wing which made up of certain characteristic thin
