Quasi-3D tangential shear deformation theory for size-dependent free vibration analysis of three-layered FG porous micro rectangular plate integrated by nano-composite faces in hygrothermal environment

A quasi-3D tangential shear deformation theory is employed to analyze free vibration behavior of a three-layered FG porous micro plate which is located between two polymeric nano-composite layers. The structure is in a hygrothermal environment and Lorentz force is applied to it. Also, it rests on an...

Description
Summary:A quasi-3D tangential shear deformation theory is employed to analyze free vibration behavior of a three-layered FG porous micro plate which is located between two polymeric nano-composite layers. The structure is in a hygrothermal environment and Lorentz force is applied to it. Also, it rests on an elastic foundation which is modeled by Pasternak type. The properties of core and faces are changed following the given functions and also are temperature-dependent. Hamilton's principle and Navier's method are employed to extract and solve motion equations, respectively. Effect of the most prominent parameters is considered and discussed in detail.
