Abstract |
|
|
| This paper presents a study on porous functionally graded piezoelectric (FGP) annular disks. The paper discussed the magneto-electric-hygrothermal effects on rotating variable thickness porous FG annular disks. Material properties coefficients and magnetic permeability are changed in a power function of radius. The disk is subjected to various loading of a uniform magnetic field, hygrothermal effect, and variation of electric potentials and mechanical pressure on the disk. A semi-analytical technique is used to get the mathematical solution of the rotating annular disk. Numerical outcomes are provided to examine the porosity factor and grading index on the rotating of the disk by different four sets of boundary conditions. The results offered a comparison between the porous and non-porous annular disks with various boundary conditions. Finally, the mathematical solution is beneficial to the planning and manufacture of a rotating porous disk influenced by complex loading and conditions. |
