In the last few years a number of numerical procedures called as meshless m
ethods have been proposed. Among them, we can mention the diffuse element m
ethod, smooth particle hydrodynamics, element free Galerkin method, reprodu
cing kernel particle method, wavelet Galerkin methods, and the so-called hp
-cloud method. The main feature of these methods is the construction of a c
ollection of open sets covering the domain which are used as support of the
classical Galerkin approximation functions. The hp-cloud method is focused
here because of its advantage of considering from the beginning the h and
p enrichment of the approximation space. In this work we present, to our kn
owledge, the first results concerning the behaviour of this technique on th
e solution of Mindlin's moderately thick plate model. It is demonstrated nu
merically that the behaviour of the method with respect to shear locking is
essentially the same as in the p-version of the finite element method, nam
ely, the shear locking can be controlled by using hp cloud approximations o
f sufficiently high polynomial degree. The computational implementation of
the method and the issue of numerical integration of the stiffness matrix a
re also discussed. Copyright (C) 2000 John Wiley & Sons, Ltd.
