Abstrakty
Detekcja uszkodzeń jest istotnym czynnikiem technicznym i ekonomicznym w eksploatacji urządzeń i konstrukcji. Za Inman i inni [1] uszkodzenie definiuje się jako zamierzoną lub niezamierzoną zmianę własności materiałowych lub geometrycznych obiektu, włączając w to warunki brzegowe, która ujemnie wpływa na aktualny i przyszły stan tego obiektu. Niezawodna i dokładna metoda nieniszczącego badania konstrukcji pod kątem wystąpienia uszkodzeń jest kluczowym elementem systemów Monitorowania Stanu Konstrukcji (SHM). Metody termograficzne są metodami bezkontaktowymi, nieniszczącymi i dającymi informację diagnostyczną dla znacznych powierzchni w trakcie jednego pomiaru (tj. zależnie od pola widzenia kamery termowizyjnej). W zależności od konfiguracji pomiarowej istnieje możliwość wykrywania wielu typów uszkodzeń. W artykule przedstawiono przegląd aktualnych rozwiązań w zakresie termograficznych metod detekcji uszkodzeń oraz opisano prace aplikacyjne prowadzone przez autorów.
Damage detection is an important issue in contemporary engineering. Following Inman et. al. [1] damage in a structural system can be defined as intentional or unintentional change to the material and/or geometric properties of the system, including changes to the boundary conditions and system connectivity, which adversely affect the current or future performance of that system. Therefore the knowledge about the existence of damage in the structure is an important element in maintenance and monitoring of structures. A reliable, accurate and nondestructive damage detection method is a key element in applications like Structural Health Monitoring (SHM) and Damage Prognosis. Nondestructive Testing (NDT) methods for damage detection can be divided into two broad groups- global and local methods. Global methods are used in monitoring of whole structures while local methods are used in monitoring of structural parts. Global methods do not require a priori information about the estimated location of damage but they are also less sensitive to small damage. Local methods on the other hand need a dense sensor network or information about critical points on the structure where the damage can occur but are more sensitive to small damage and sometimes can identify the type of damage. There are many approaches for damage detection in each group, and thermographical methods combine the advantages of both. In recent years thermography has emerged as a widely used method for nondestructive testing. Thermography is a nondestructive, noncontact, wide area damage detection method. It can detect subsurface defects, and can be used as an alternative or complement to conventional inspection technologies. Of special interest due to the effectiveness is vibrothermography also referred to as ultrasound thermography. The paper presents the state-of-the-art in thermographical damage detection techniques and describes some of the experimental investigations carried out by the authors.
