Aplicación del método de elemento finito al análisis nodal

The first four natural modes of vibration of a beam with type I section subjected to different conditions were studied. Results were obtained analytically, experimentally and numerically. The later ones by using commercial finite element packages (Patran™ and Abaqus™). A comparison of the three techniques used is presented as well as the advantages of the finite element method (FEM). A brief introduction to FEM is presented, and an overview of the chances of research using this technique.
