Abstract
The displacement-based formulation of the method of nite spheres is observed to exhibit volumetric
`lockingʹ when incompressible or nearly incompressible deformations are encountered. In this paper,
we present a displacement=pressure mixed formulation as a solution to this problem. We analyse the
stability and optimality of the formulation for several discretization schemes using numerical inf{sup
tests. Issues concerning computational e ciency are also discussed
