Adhesive bonding technology is a boon in industrial applications that are highly advantageous over conventional fastening processes such as welding, riveting, soldering, and brazing. Adhesively bonded plate structures offer great design flexibility, uniform stress concentration, good damping properties, high corrosion resistance, high dynamic strength, a marginal increase in the weight of the assembly, and so on. Adhesively bonded plate structures have many applications particularly in aerospace, aeronautical, shipbuilding, aircraft construction, marine, and automotive industries when subjected to a permanent types of loading majorly, vibrations. The present work aims at using the simulation approach to extract the vibration characteristics like natural frequencies and mode shapes for the base plate and adhesively bonded plate joint with different configurations like varying overlap length and boundary conditions by using Ansys software. For the validation of simulation results, experimentation is carried out for all the configurations. The outcomes reveal the significant impact of plate thickness overlap length and boundary conditions on the vibration characteristics.
