- Abstract
Purpose: The present research paper focuses on the free in-plane vibrational analysis of a curved cracked cantilever beam using experimental and computational methods with reuse of aluminum scrape. Method: The equation of motion governing free in-plane vibration of a curved cantilever beam with a single crack is solved numerically via DQEM (Differential Quadrature Element Method). Additionally, the fundamental frequencies and mode shape are investigated at various curvatures and depths of the curved cracked beam. Results: The results are compared to the experimental model and finite element method to confirm the correctness of the suggested method of calculating its natural frequencies and mode shapes. Conclusion: This study shows that the boundary conditions of the beam affect how a curved beam behaves concerning the mode transition event. The present method can also predict the impact of damage severity and location on a curved beam's natural frequencies and mode shapes.
