摘要:The infrared thermography has been developed for Non-Destructive Testing (NDT), stress analysis, and in the last 10 years for metal fatigue assessment. The present research enables to realize these different research objectives all together thanks to an innovative experimental procedure, which includes NDT by lock-in thermography, thermoelastic stress analysis, and fatigue parameters assessment by Rapid Thermographic Method (RTM). The developed procedure has been performed on a set of hole-notched specimens, achieving good results and predictions in a relatively short time. Moreover, the fatigue strength reduction coefficients of the specimens were determined by RTM. This thermography-based approach is dedicated for structural analysis and fatigue evaluation; it is an interesting attempt to apply different thermographic methods to a common research topic.
