International Journal for Numerical Methods in EngineeringAccepted Paper A. Ortiz-Bernardin, R. Silva-Valenzuela, S. Salinas-Fernández, N. Hitschfeld-Kahler, S. Luza, B. Rebolledo Abstract We propose a combined nodal integration and virtual element method for compressible and nearly incompressible elasticity, wherein the strain is averaged at the nodes from the strain of surrounding virtual elements. For the strain averaging procedure, a nodal averaging operator

Computer Methods in Applied Mechanics and Engineering Vol. 119, No. 25-28, pp. 1859-1871, 2010 A. Ortiz , M.A. Puso, N. Sukumar Abstract Numerical integration errors and volumetric locking in the near-incompressible limit are two outstanding issues in Galerkin-based meshfree computations. In this paper, we present a modified Gaussian integration scheme on background cells for meshfree
