This research aims to investigate the deformation properties of auxetic textile structure using Ansys software. Auxetic structures exhibit unique mechanical behavior, including negative Poisson’s ratio, which makes them promising for various technical textile and engineering applications. This study explores the deformation characteristics under different loading conditions. A 3D model of the re-entrant auxetic structure with a thickness of 3 mm is created and meshed using Ansys software. Material properties of polylactic acid (PLA) and boundary conditions are defined. Various loading scenarios, including bending and compression, are simulated by applying forces at specific distances from reference points, that is, the center of the structure for synclastic curvature and from the center of the side walls for compressive strength. Ansys software is utilized to perform structural analysis, capturing total deformation and stress distribution. Synclastic curvature for bending and compressive strength for compression are the primary focus which are worked on Ansys workbench. The analysis reveals that when subjected to bending forces, auxetic textile structure exhibits a significant synclastic curvature, making it viable for 3D printing. This behavior suggests its potential for applications requiring flexibility and adaptability. Under compressive loading, the auxetic structure demonstrates remarkable compressive strength, with minimal deformation. This characteristic makes it suitable for applications where load-bearing capabilities are critical. The auxetic textile structure with a 3 mm thickness exhibits pronounced synclastic curvature during bending, indicating its suitability for applications that require flexibility and shape adaptation suitable to be developed as a 3D-printed auxetic textile structure. The structure exhibits impressive compressive strength with minimal deformation under load, making it a promising candidate for load-bearing applications in engineering and textiles.
