Three-Dimensional Finite Element Modeling of Double-Twisted Hexagonal Mesh

Abstract

Abstract The mesh structure based on double-twisted hexagonal grids is an important part of reinforced gabion structures. Due to challenges in sensor placement during physical experimentation on complex gabion mesh mechanical properties, numerical simulation serves as a valuable means of study, with accurate numerical grids being integral to obtaining reasonable results. This article proposes a novel approach for constructing a numerical model that incorporates unique geometric features. The approach categorizes mesh wire types into three groups based on their geometric structure and presents a relational equation governing the motion of a single wire axis during manufacturing. Secondly, A three-dimensional finite element model of a double-twisted hexagonal mesh was constructed using ABAQUS software to simulate a quasi-static uniaxial tensile experiment. Finally, the proposed approach was validated by comparing its numerical and experimental results, supporting its rationality. Additionally, it addresses the limited availability of three-dimensional numerical models for gabion meshes, thereby offering potential for further research on the mechanical properties of gabion structures under complex working conditions.
