In this paper, for the first time, the bending and free vibration analysis of porous functionally graded sandwich (PFGS) plates is investigated using a higher-order shear deformation theory (HSDT) C0 type and finite element model. This construction consists of a single homogenous ceramic core and two distinct functionally graded skins. The mechanical results related to bending and free vibration behaviours of it are searched using the Matlab software. The other plates with different materials or arbitrary forms can use this code as well in the future. To verify the procedure's potential of use, the study's findings are contrasted with those of previous studies in the literature. Additionally, the effects of a number of parameters on the bending and vibration of PFGS plates are provided, including the porosity factor, volume fraction index, and geometric ratio. These results show that the distribution of porosity plays a significant role in the mechanical properties of PFGS plates.
