DOI: 10.1002/nme.6698

Abstract: To identify the superconvergent areas of gradient solutions is a worthwhile part of gradient recovery in finite element method. Compared with triangular and quadrilateral elements, the position determination for the superconvergent gradient of polygonal element… read more here.

DOI: 10.1016/j.cma.2018.08.014

Abstract: Abstract This paper introduces a general recovery-based a posteriori error estimation framework for the Virtual Element Method (VEM) of arbitrary order on general polygonal/polyhedral meshes. The framework consists of a gradient recovery scheme and a… read more here.

DOI: 10.1142/s0218202519500386

Abstract: Virtual element method is a new promising finite element method using general polygonal meshes. Its optimal a priori error estimates are well established in the literature. In this paper, we take a different viewpoint. We… read more here.

DOI: 10.1155/2017/5903503

Abstract: This research purposed a new family of finite elements for spherical thick shell based on Nzengwa-Tagne’s model proposed in 1999. The model referred to hereafter as N-T model contains the classical Kirchhoff-Love (K-L) kinematic with… read more here.
