Abstract in different language: Infrared nondestructive testing (IRNDT) is an active thermography method for inspection of material-surface inhomogeneities or discontinuities. It is based on an excitation of an inspected sample and a detection of its thermal response by thermographic methods. The IRNDT is commonly used for an inspection of delaminations. However, it is also applicable for surface and subsurface cracks detection, which is the focus of this contribution. Principles of IRNDT methods are introduced in this contribution. Flash-illumination, ultrasonic-loading, laser-heating and mechanical-loading excitation methods, which are mostly used for cracks detection, are described. Examples of results of an IRNDT inspection of cracks by different approaches are presented.
