Consistent and stable meshfree Galerkin methods using the virtual element decomposition

International Journal for Numerical Methods in Engineering Volume 112, Issue 7, 2017, pp 655-684 A. Ortiz-Bernardin, A. Russo, N. Sukumar Abstract Over the past two decades, meshfree methods have undergone significant development as a numerical tool to solve partial differential equations (PDEs). In contrast to finite elements, the basis functions in meshfree methods are smooth (nonpolynomial functions),…

Paper Accepted: Linear smoothed polygonal and polyhedral finite elements

Paper Accepted for Publication in International Journal for Numerical Methods in Engineering A. Francis, A. Ortiz-Bernardin, SPA. Bordas, S. Natarajan, “Linear smoothed polygonal and polyhedral finite elements.” ABSTRACT It was observed in [1, 2] that the strain smoothing technique over higher order elements and arbitrary polytopes yields less accurate solutions than other techniques such as…
