RESEARCH ON FREE VIBRATION CHARACTERISTICS OF THIN PLATE STRUCTURES BASED ON IMPROVED FOURIER SERIES
Published 2025-06-01“…Aiming at the problem of structural vibration modeling and characteristic analysis of rectangular sheets under arbitrary boundary conditions, an improved Fourier series method was proposed.Based on the Rayleigh-Ritz method, the allowable function of vibration displacement of thin plates was expressed as a linear combination of double Fourier cosine series function and auxiliary series function, which effectively avoided the possible discontinuities or singularities of the traditional Fourier series at the boundary. …”

Vibration-Based Damage Prediction in Composite Concrete–Steel Structures Using Finite Elements
Published 2025-01-01“…The approach effectively captured stiffness degradation in the model, leading to observable changes in modal responses, including a reduction in natural frequencies and variations in modal shapes. This enabled the accurate prediction of damage instances during construction, service, or accidental load scenarios, thereby enhancing the structural and operational safety of composite system designs. …”
