<p>Stochastic first three natural frequencies of hybrid composite plates were determined by employing the finite element (FE) based numerical approach. Shape memory alloy (Nitinol) in the shape of fiber was inserted in glass epoxy composite plates to obtain the hybrid composites. A comprehensive study was carried for stochastic quantification of natural frequencies of the hybrid composites due to stochastic dissimilarity in the material and geometrical properties. The effects of degree of stochasticity, effect of specific volume, effect of change of martensite fraction, effect of ply orientation angle, and effect of staking sequence on the first three natural frequencies were determined by finite element method coupled with Monte Carlo simulation. The results demonstrated that increasing the degree of stochasticity significantly impacts the natural frequencies, broadening their range. Additionally, the analysis revealed that higher martensite fractions lead to a decrease in the natural frequencies. The study also explored the influence of ply orientation angle, stacking sequence, thickness, and specific volume on the natural frequencies.</p>
