Obtenció dels modes de resonancia a una geometria complexa: proposta didàctica de modelització amb elements finits

Finite Elements Method is a well established mathematical technique for solving Partial Derivative Differential Equations. In this article we present an example of application of Finite Elements Method: the harmonic resonance modes of a guitar obtained from the resolution of the eigenvalues equation via the Finite Elements Method. Graphical output and direct comparison with experiments facilitates the understanding of the method and an extra motivation, establishing a link between Mathematics and the resolution of real engineering problems than is specially necessary in the teaching of Mathematics in the engineering schools.
