Abstract
This paper presents the buckling analysis of the piezoelectric functionally graded
material (FGM) rectangular plates subjected to non-uniformly distributed loads,
heat and voltage based on the mesh-free method. A two-step solution procedure
is implemented. The first step is to determine the pre-buckling stresses of the
plates subjected to non-uniformly distributed loads. The second step is to solve
the buckling loads and buckling temperatures. The variational form of the system
for the calculation of pre-buckling stresses is based on a two-dimensional (2D)
plane stress problem, and the variational form with penalty method of the plates
for the calculation of buckling loads and buckling temperatures is based on the
Mindlin plate assumption. The displacement is approximated using the moving
least squares (MLS) technique based on a set of scattered nodes. Two numerical
examples are presented to validate the proposed mesh-free method.
Keywords: functionally graded plate, moving least squares, buckling analysis,
non-uniformly distributed load, heat, voltage.
1 Introduction
Functionally graded materials (FGMs) are a mixture of two or more materials in
such way that their material volume fractions vary continuously along certain
