Abstract

In this article, we will investigate the local ultraconvergence of the displacement and derivative of finite element solution using piecewise polynomials of degrees k (k ≥ 2) by Richardson extrapolation operators P1k and P2k presented in He et al. for second‐order elliptic problems with singularity. Numerical results are provided to illustrate the theoretic findings. [ABSTRACT FROM AUTHOR]
