Relationship between growth and temperature at the tip of the fatigue crack in AISI 1018 steel

In this work, a study dealing with the correlation between the fatigue crack growth behavior and the temperature evolution at the tip of the fatigue crack of the AISI 1018 steel is presented. Both the crack length and the temperature at the crack tip were experimentally obtained from a fatigue test...

Both the crack length and the temperature at the crack tip were experimentally obtained from a fatigue test carried out according to the ASTM E647; the temperature at the crack tip was simultaneously acquired by thermocouples and infrared thermography, while the crack length was acquired through a microscope. The experimental data were processed aimed at plotting the curves of the temperature against cycles as well as the crack length against cycles in order to be able to correlate the information and, therefore, to obtain by linear regression of the experimental data a model to correlate the temperature at the crack tip to the crack length. The results showed that, on one hand, the linear regression is in good agreement with the experimental data, and, on the other hand, the proposed model allows for estimating the trend and the magnitude of the temperature when the crack grows. En este artículo se presenta un estudio sobre la relación que existe entre el comportamiento del crecimiento de grieta por fatiga y la evolución de la temperatura en la punta de grieta en un acero AISI 1018. Tanto la longitud de la grieta como la temperatura se obtuvieron experimentalmente de ensayos de fatiga de acuerdo a la norma ASTM E647. La temperatura se midió simultáneamente a través de termopares y termografía infrarroja, mientras que la longitud de la grieta se midió a través de un microscopio. Los datos experimentales se procesaron para obtener curvas de ciclos contra temperatura y ciclos contra longitud de grieta para posteriormente correlacionar la información y obtener, por regresión lineal de los datos experimentales, un modelo para relacionar la temperatura con la longitud de la grieta. Los resultados muestran que el modelo propuesto está en buena concordancia con los datos experimentales y permite estimar la tendencia y la magnitud de la temperatura al crecer la grieta.
