Stress-induced anisotropy, the directional variation in soil properties under applied loads, significantly influences the soil behavior and stability of geotechnical structures. This review critically examines its impact on shear strength, pore pressure, stiffness, and stress-strain behavior of soils, offering insights into its fundamental mechanisms. Advancements in experimental methods, including bender element tests, true-triaxial testing, and hollow cylinder apparatus, are critically analyzed alongside analytical and numerical models that capture complex anisotropic responses under varied loading conditions. The study highlights the practical significance of incorporating the anisotropic behavior of soils in geotechnical design. From the literature, it can be concluded that neglecting stress-induced anisotropy can overestimate the factor of safety (FOS) of slopes up to 33% and underestimate displacements of foundations by 25-40%, leading to critical inaccuracies in the design. A case study of slope failure under anisotropic stress highlights the necessity of accounting for these effects. Challenges such as replicating realistic stress paths in laboratory tests and integrating anisotropic parameters in numerical frameworks are identified. Future directions include developing predictive models, automating analysis using machine learning, and validating findings through large-scale field studies. This review bridges theoretical advancements with practical applications, advocating for integrating stress-induced anisotropy, wherever applicable, into geotechnical practice to enhance infrastructure safety and resilience.
