Integration of DQM and FSDT improves natural frequency predictions in sandwich plates, suggesting enhanced design strategies.

Optimizing fiber paths increased the fundamental frequency of sandwich plates by up to 32.7%.
Results showcased a maximum error of less than 5% using a 19 × 19 mesh with the integrated approach.
The study validated the approach by comparing outcomes with traditional FSDT-based results, showing excellent agreement.
The analysis explored how fiber orientation and other parameters influenced the natural frequency of composite plates.
