Abstract
This article presents apparently the first application of Meshless local Petrov-Galerkin
(MLPG) method for 3-D elasticity analysis of moderately thick rectangular laminated plates. As
with other Meshless methods, the problem domain is represented by a set of spread nodes in all
three dimensions of the plate without configuration of elements. The Moving Least-Squares (MLS)
method is applied to construct the required shape functions. A local asymmetric weak formulation
of the problem is developed and MLPG is applied to solve the governing equations. Direct
interpolation method is employed to enforce essential boundary conditions. Details of formulation,
numerical procedure, convergence and accuracy characteristics of the method are investigated.
Results are compared, where possible, with other analytical and numerical methods and show good
agreement.
