ABSTRACT: Double-beam systems have attracted significant attention due to their unique mechanical behavior and wide range of engineering applications. This study offers an extensive review of the mechanics and applications of double-beam systems, addressing both theoretical progress and practical uses. Initially, the theoretical foundations, including Euler-Bernoulli and Timoshenko beam theories, higher-order shear deformation models, and advanced non-local elasticity and strain gradient theories for micro- and nano-scale applications are reviewed. In addition, the role of elastic and viscoelastic interlayers-modeled by Kelvin-Voigt, Maxwell, Burgers, and Zener approaches is discussed, as well as the influence of different foundation models such as Winkler, Pasternak, and Kerr. The literature survey traces the historical evolution of double-beam research, from early vibration and stability studies in the 1970s to recent advances involving functionally graded materials, cracked beam analyses, and moving load problems. Future research directions include the development of smart material-based double-beam systems, broader adoption of computational methods, and coupling theoretical models with experimental approaches. These perspectives underline the importance of double-beam systems not only in structural mechanics but also in advanced engineering applications.
