The material properties of geotextiles play a significant role in shaping the long-term behavior of reinforced soils, potentially leading to issues like instability and excessive deformation. To address these challenges, thorough research into geotextile materials' rheological properties and nonlinear behavior is essential. This study specifically focuses on the investigation of six commonly employed isotropic hyperelastic models (Neo-Hooke, Mooney-Rivlin, Ogden, Yeoh, Arruda-Boyce, and Van der Waals) for describing the behavior of PET woven geotextiles in civil engineering applications. These models are fine-tuned through uniaxial tension tests conducted in warp and weft directions. Upon analyzing the experimental data, it becomes evident that the Yeoh and Neo-Hooke models exhibit exceptional accuracy in predicting geotextile behavior. The primary objective of this study is to advance our comprehension of how geotextiles react to varying loads, achieved through a combination of testing and finite element simulations. The robust correlation between experimental and simulation results significantly contributes to developing dependable hyperelastic material models tailored for geotextiles. This research framework holds considerable potential value for manufacturers and engineers as it equips them with practical tools to address concerns associated with soil-structure interaction in their projects.
