Non-destructive indentation testing is a method used to assess the mechanical properties of materials without causing permanent damage. In the context of structural integrity inspection, this technique can be employed to evaluate the strength, stiffness, and hardness of various components, such as concrete, steel, and composite materials. By applying a controlled load to the material’s surface and measuring the resulting indentation, we can gain valuable insights into its mechanical behavior and identify potential defects or weaknesses. This approach is particularly useful for inspecting critical structures like bridges, buildings, and aircraft, where maintaining structural integrity is paramount.
