STUDY OF AN ELASTIC BEAM, IN CENTRIFUGAL FIELD, USING FINITE ELEMENT METHOD
The finite element method (FEM) has been applied mainly to the study of the behavior of different elastic bodies, whether static or dynamic. The case of rigid motion of bodies analyzed with MEF, involving new terms due to the effects of inertia and relative motions, has not yet been incorporated into the classic MEF software. Papers to analyze this behavior arose in the 70's for the plane beam and later for a three-dimensional general motion. The present paper aims to develop models previously studied by other researchers and study the influences that the geometric parameters of the bar can have on the dynamic response. The case study is that of a moving bar in a rotation around a fixed axis. The shape functions used are of degree five.
Key words: Finite Element Method, beam, eigenvalues, eigenmodes, rotation, centrifugal
