The present work shows the modal analysis of tri-directional advanced composite beams using the finite element method. The mechanical parameters of the beam are supposed to vary in the direction of beam length (x), width (y), and thickness (h). In this work material parameters are assumed to vary according to the exponential rule of functionally graded material. To authenticate the accuracy of the present work, the result with a particular case is compared with those obtained by previously published work (Bi-directional beam) for a reduced case. Satisfactory results have been achieved. The influence of exponent parameters and end conditions on the natural frequency of the tri-directional advanced composite beams is reported. It has been observed that increasing the exponent parameters in the width direction results in a decrease in natural frequency for all four modes. Similarly, increasing the exponent parameter in the length direction also leads to a decrease in natural frequency for all modes. Furthermore, it can be concluded that as the length-to-thickness ratio increases, the natural frequencies decrease. In this work, COMSOL Multiphysics Software is used to obtain natural frequencies. The tailored mechanical properties of tri-directional advanced composite materials make them highly advantageous for use in aircraft structures.
