Purpose: This study provides a comprehensive examination of the free vibration responses exhibited by adhesive-bonded double lap joints. The outcomes derived from this approach provide invaluable insights for optimizing the performance and stability of adhesive-bonded double lap joints in engineering applications. Methods: To assess the natural frequencies of these joint structures, a finite element analysis is employed. The natural frequency parameters obtained are then compared with existing literature, revealing a strong concurrence that substantiates the precision and consistency of the study. The investigation delves into the influence of various design parameters, including material properties, stacking patterns, and aspect ratios, on the modal analysis of these joint structures. Results: This research conducts a significance and sensitivity analysis to assess the impact of diverse factors on the natural frequencies of adhesive joints. Utilizing an analysis of variance (ANOVA) method, modal frequencies can be predicted. Outcomes revealed that one-sided fixed support results in a 79% lower natural frequency, and modal frequencies increase with changing elasticity-to-adhesive ratios. Plate length has the most significant influence on modal frequencies, and the ANOVA analysis yielded an average error of 2.871%. Conclusions: This study found that the combination of Poisson's ratio and shear modulus significantly impacts the vibration of glass/epoxy double lap joints. [ABSTRACT FROM AUTHOR] |
