Diagnosing health of materials and structures

A Russian institution offers a newly developed device for the effective and reliable diagnosis of materials and structure failures. Employing a television-optical measuring method and an acoustic diagnostic unit, this highly specialised system may be used in widespread applications. These may be simple investigations of mechanical deformations or more complex non-destructive testing of parts and structures of vital equipment, such as pipelines and boilers.
Diagnosing health of materials and structures
The offered diagnostic device is an integrated system that uniquely combines a television-optical measuring technique and acoustic diagnostics for testing materials and structures. This innovative device employs essentially unique image processing capabilities for close investigation of the micro-relief of the surface of the material under study. This information may be coupled with an in-depth analysis of the characteristics of the acoustic signals of parts and structures under loading conditions.

The device may scan large areas scanning (37x45mm²) with a high resolution of the order of 0.4mm and may store as much as 100 measurements. Its overall dimensions and weight allow its easy transportation, which is of great value particularly for construction industries developing structures at various sites. The device may be used in non-destructive testing studies and pre-fracture diagnostics of expensive machines and equipment such as pipelines, compressors, tanks and boilers.

The diagnostic system may provide accurate and reliable measurements of the mechanical properties of local regions of materials under investigation. In addition, it may lead to timely and effective prognosis of fractures of parts and structures even before micro-crack nucleation. In this way, it could offer valuable assistance in preventive maintenance activities for extending the life cycle of various machines, structures and equipment.
