Abstract
The article discusses the areas of effective application, the features of heat generation and the main possibilities of the passive method of thermal non-destructive testing of steel elements and products. The basic requirements for passive thermal control equipment are formulated. The mechanism of heat generation in steel is described and the structure of the formula for changing its temperature during deformation is substantiated. It is shown that the diagnostics of steel elements in the passive mode should be carried out with the functioning of heat sources in them, arising as a result of force effects on structures. The features of determining the stress state in steel elements by the passive thermal method are considered.
It is shown that the passive method of thermal non-destructive testing of steel structures, loaded with continuously increasing or decreasing forces in time, under the influence of which internal deformation heat sources and surface temperature fields function in potentially dangerous zones of elements, makes it possible to control the operability in elastic, elastic-plastic stages of steel operation, the origin and development of destruction. The power of thermal deformation sources, the places of their occurrence and the kinetics of development depend on the conditions of force loading, external temperature influences, material and structural shape of the elements.
