The present work aims to study the free vibration of Timoshenko beams applied to functionally graduated materials; This is solved using the finite element method (FEM), when implemented in the MATLAB software, in order to obtain the fundamental frequencies and the graphs of the vibration modes for each case. The field of displacements is defined according to the Timoshenko theory considering three fundamental variables; likewise, the Hamilton Principle is used to obtain the free vibrations of the element. For the development of the constitutive relationships, the power law is used, which describes how the properties of a heterogeneous and isotropic material FGM vary in the heightn of the beam. The results obtained were compared with other literature studies validated by journals such as SCOPUS and SPRINGER, showing that the model is quite accurate and satisfactory.
