In this study, the free vibration analysis of a skew sandwich plate is conducted utilizing the Radial Basis Collocation Method (RBCM). Using HSDT, the free vibration response of a skew sandwich plate has been determined. Hamilton's approach is used to get the GDEs, which are then discretized using the RBF. The accuracy and efficiency of the RBCM in predicting the vibration and mode shapes of the skew sandwich plate are demonstrated through a comparison with results obtained from existing analytical and numerical methods. The impact of various parameters on the dynamic response of the plate is analyzed, providing valuable insights into the design and optimization of skew sandwich structures. Findings from the open literature are used to validate the current findings. Examined are the effects of the skew angle, core-to-face thickness ratio, and span-to-thickness ratio on the frequency.
