Abstract

This paper presents a novel triangular strain-based element designed to address plane stress and strain, axisymmetric, and dynamic problems. The proposed element has four nodes, three of which are located at the vertices and one of which is located at the midpoint of the diagonal. The corner nodes have three essential external degrees of freedom (u, v, θ), while the central node has two degrees of freedom (u, v) on one of the triangle edges. A static condensation-based treatment of the central node is employed to streamline the model and reduce computational overhead. This triangular element is applicable to both linear and dynamic analyses. Its performance is evaluated using a suite of membrane and axisymmetric problems. The obtained results demonstrate the robustness and accuracy of the proposed element.
