Determination of Fatigue Limit by Static Thermographic Method and Classic Thermographic Method on Notched Specimens [PDF]
Procedia Structural Integrity, 2020 Abstract The aim of the present work is to investigate the possibility to evaluate the fatigue limit of such a component through the so-called Static Thermographic Method (STM). This new approach has been proposed in 2013 by Risitano and Risitano to determinate the fatigue limit of metallic materials through static tensile tests.
