| Popis: | Purpose In this paper, a new quadrilateral strain-based element is developed. 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. |
