Analytical Solution for Free Vibration of Multi-Cracked Metal–Ceramic Functionally Graded Nanobeams Resting on Elastic Foundations Akash Kumar Gartia, Priya Rao, S. Chakraverty International Journal of Structural Stability and Dynamics, 2025 This study explores the free vibration behavior of multi-cracked functionally graded (FG) nanobeams situated on Winkler–Pasternak elastic foundations. Cracks are modeled as rotational springs, effectively dividing the beam into sub-beams. The present model is formulated for metal–ceramic FG nanobeams composed of two isotropic phases with material properties varying continuously across the thickness based on a power-law distribution. The analysis incorporates Euler–Bernoulli beam theory and Eringen’s nonlocal elasticity theory to capture size-dependent effects. A fourth-order differential equation with constant coefficients is formulated, and an analytical approach is utilized to calculate the frequency parameter values. Validation with existing literature in specific cases confirms the accuracy of the obtained results. The effects of various factors, including the transverse gradient index, nonlocal parameter, Winkler and Pasternak foundation parameters, crack severity, and crack locations, on the first four frequency parameters are investigated. Unlike existing studies, the proposed model allows for any number of cracks (multiple cracks), offering a generalized framework for realistic damage scenarios. This is the first study to analytically address the combined effects of multiple cracks with elastic foundations in FG nanobeams. This framework provides a robust tool for analyzing FG nanobeams with cracks under diverse boundary conditions and material gradations. These findings have significant implications for the design and optimization of nanostructures in aerospace, mechanical, and biomedical applications.
