Abstract
The paper deals with transient analysis of homogeneous as well as FGM (functionally graded
material) thin micro/nano plates subjected to transversal dynamic loading. within the highergrade continuum theory of elasticity. The microscopic structure of material is reflected in this
higher-grade continuum theory via one material coefficient called the micro-length scale
parameter. Furthermore the material can be composed of two micro-constituents what is included
in the employed continuum model by functional gradation of the Young’s modulus through the
plate thickness with assuming power-law dependence of volume fractions of micro-constituents
on the transversal coordinate. The high order derivatives of field variables are eliminated by
decomposing the original governing partial differential equations (PDE) into the system of PDEs
with lower order derivatives. For the numerical implementation, the weak formulation is proposed
with novel Moving Finite Element approximation method of spatial variations of field variables.
The semi-discretized equations of motion yield a system of ordinary differential equations which
can be solved by standard time stepping techniques. Several numerical simulations are devoted to
study the influence of micro-length scale parameter as well as the parameters of gradation of
Young’s modulus on coupled bending and in-plane deformation response modes.
