Nonlinear vibrations of moving functionally graded plates containing porosities and contacting with liquid: internal resonance

Nonlinear vibrations of longitudinally moving functionally graded material (FGM) plates containing porosities and contacting with liquid are investigated. The FGM plates contain porosities because of technical issues during the FGM preparation. Two types of porosity distribution, namely even and uneven distribution, are taken into account. The liquid is assumed to be incompressible, inviscid and irrotational. The velocity potential along with...
