What are the latest non-destructive testing techniques for structural mechanics?

2 Digital Radiography

Digital radiography (DR) is a NDT technique that uses X-rays or gamma rays to penetrate a structure and capture an image of its internal features on a digital detector. DR can provide high-quality images of the structure and its defects in real time, with less radiation exposure and waste than conventional film radiography. DR can also enhance, analyze, and store the images digitally for further evaluation. DR is commonly used for structural mechanics applications such as aerospace inspection, pipeline inspection, and concrete inspection.

3 Infrared Thermography

Infrared thermography (IRT) is a NDT technique that uses a thermal camera to measure the surface temperature of a structure and display it as a thermal image. IRT can reveal the thermal anomalies that indicate defects, damage, or deterioration of the structure. IRT can also monitor the heat flow and thermal performance of the structure under different conditions. IRT is often used for structural mechanics applications such as building envelope inspection, bridge inspection, and composite inspection.

4 Acoustic Emission

Acoustic emission (AE) is a NDT technique that detects the sound waves generated by the structure when it undergoes stress, deformation, or fracture. AE can monitor the structural integrity and identify the location and severity of the defects in real time. AE can also assess the fatigue life and damage accumulation of the structure over time. AE is frequently used for structural mechanics applications such as pressure vessel inspection, wind turbine inspection, and structural health monitoring.

5 Laser Scanning

Laser scanning is a NDT technique that uses a laser beam to scan the surface of a structure and measure its shape, dimensions, and features. Laser scanning can create a 3D model of the structure with high accuracy and resolution. Laser scanning can also compare the actual structure with the design specifications or previous scans to detect any deviations, deformations, or displacements. Laser scanning is widely used for structural mechanics applications such as surveying, alignment, and deformation analysis.
