finite element approach to the prediction of foil

The inverse Finite Element Method was adapted by Gherlone for shape sensing of truss beam and frame structures Since the initial introduction of iFEM the approach has been successfully applied on a variety of simple and complex structures where the focus has been primarily on the small deformation linear load-displacement response In our finite element approach each layer is a Reissner-Mindlin-von Krmn plate accounting for bending shear and membrane strain energies Moreover the thickness of the interlayer is explicitly included in our approach and therefore it is stiffer

Subfoil Stiffness Effects in Gas

A finite element foil bearing model that incorporates radial and circumferential deflections of a corrugated sub-foil into the prediction of rotor dynamic coefficients is presented The corrugated sub-foil is treated as a continuous structure that supports the top-foil Radial and circumferential deflections are coupled in the sub-foil

Finite Element Method: In this method of analysis a complex region defining a continuum is discretized into simple geometric shapes called finite elements The material properties and the governing relations are considered over these elements and expressed in terms of unknown values at element corner
