A new formulation of the Element Free Galerkin (EFG) method is developed for the modelling of incompressible materials. Beginning with a mixed variational principle, a selective reduced integration procedure is developed by implementing nodal quadrature. Numerical examples are provided which compare

## Abstract The meshless methods, namely the element‐free Galerkin method (EFGM), when they first appeared claimed that volumetric __locking__ and __hourglass__ were avoided. This was not the case and both phenomena occur in the EFGM. In the context of the finite element method (FEM) these phenomen
