Linear smoothed polygonal and polyhedral finite elements

International Journal for Numerical Methods in Engineering Volume 109, Issue 9, 2017, pp 1263–1288                                                                                                                            A. Francis, A. Ortiz-Bernardin, SPA. Bordas, S. Natarajan 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 the conventional polygonal finite element method.
