Title: Prognostic Assessment of Symmetric Perpendicular Edge Cracks on the Vibration Characteristics of Orthotropic Cantilever Composite Plates
Contributor:
Group publication title:
Abstract:
This study investigates the free vibration characteristics of orthotropic cantilever composite plate containing symmetric double edge cracks. A detailed finite element analysis (FEA) was conducted in ANSYS APDL to investigate the influence of crack length (a/W=0 0.04) and crack location (x_c/L=0-0.75) on the first six natural frequencies. The results show a consistent frequency reduction with increasing crack length and proximity to the clamped edge, while higher-order modes display greater sensitivity due to localized strain energy near the cracks. ; A semi-empirical relation was also developed to predict frequency degradation based on crack geometry and position, achieving excellent agreement with numerical data (R^2>0.99). The findings provide a concise framework for vibration-based damage detection and structural health monitoring (SHM) of orthotropic composite structures. Unlike previous works that primarily examined single-edge or isotropic configurations, this study uniquely quantifies the coupled influence of symmetric double-edge cracks in orthotropic cantilever plates, thereby extending the understanding of multi-crack interaction effects in composite dynamics.
