Hybrid smoothed finite element method for acoustic problems
Computer Methods in Applied Mechanics and Engineering, 2015 It is well known that "overly-stiff" finite element (FE) model fails to provide accurate results to the Helmholtz equation with large wave numbers due to the well-known "pollution error" caused by the numerical dispersion.

Smoothed finite element method for two-dimensional elasto-plasticity [PDF]
Vietnam Journal of Mechanics, 2009 This communication shows how the smoothed finite element method (SFEM) very recently proposed by G. R. Liu [14] can be extended to elasto-plasticity. The SFEM results are in excellent agreement with the finite element (FEM) and analytical results.
