During the manufacturing process of materials and assemblies, structural defects can occur. Thin plates used in industrial engineering typically have thicknesses of a few millimeters or less, making it impossible to use conventional non-destructive testing methods such as ultrasound or eddy currents. As a result, knowledge of their internal integrity is not possible.This study highlights the natural vibration modes of the plates by identifying specific frequencies in modal analysis to avoid overlapping in operation, which can lead to resonance and rapid destruction of the structure when it exits the assembly's service. In addition, a source study of variable frequency vibrations was conducted to observe the design (arrangement) of nodes and antinodes on the thin plates studied. This is necessary to prepare the technical framework that validates the use of vibrations for non-destructive testing of thin plates.
