粘弹性地基上功能梯度材料薄板的自由振动
Free vibration of functionally graded thin plates resting on viscoelastic foundations
摘要
Abstract
For obtaining the vibration performance of functionally graded thin plates resting on viscoelastic foundations,based on the theory for mechanical properties of functionally graded materials varied with thickness direction according to a simple power distribution and the motion differential equations of thin functionally graded plates,the semi-analytical solutions of free vibration of the plates resting on viscoelastic foundations with various boundaries are obtained by multi-modal analysis method and Galerkin procedure.The results of parameter analysis show that natural frequencies decrease with the increase of volume fraction index and viscous parameter of viscoelastic foundation,and rise with the increase of stiffness parameters of viscoelastic foundations and the decrease of side-to-thickness ratio.关键词
