Abstract

Purpose
The purpose of this paper is to develop a new quadrilateral strain-based element. The element has five nodes, four at the corners as well as an internal node.

Design/methodology/approach
Through the introduction of the internal node, the numerical performance of the element proved to be superior to existing elements in the literature, even though a static condensation is required.

Findings
From several numerical examples, it is shown that convergence can be achieved with the use of only a small number of finite elements. The proposed element can be used to solve general plane linear elasticity problems resulting in excellent results.

Originality/value
The results obtained are comparable with those given by the robust element Q8.
