{wiki=Impulse_excitation_technique}
The Impulse Excitation Technique (IET) is a non-destructive testing method used to characterize the mechanical properties of materials, particularly in terms of their elastic properties. This technique is often employed in the fields of materials science, structural engineering, and quality control for various materials including metals, ceramics, composites, and polymers. \#\#\# Basic Principles: 1. **Impulse Generation**: The process begins by applying a mechanical impulse to the material or component being tested.
