Study of the stress intensity factors in the bulk of the material with synchrotron diffraction López-Crespo, Pablo Vázquez Peralta, Javier Simpson, C Moreno-Morales, María Belén Buslaps, T Withers, Philip J. Estrés (Fisiología) In this work we present the results of a hybrid experimental and analytical approach for estimating the stress intensity factor. It uses the elastic strains within the bulk obtained by synchrotron X-ray diffraction data. The stress intensity factor is calculated using a multi-point overdeterministic method where the number of experimental data points is higher than the number of unknowns describing the elastic field surrounding the crack-tip. The tool is tested on X-ray strain measurements collected on a bainitic steel. In contrast to surface techniques the approach provides insights into the crack tip mechanics deep within the sample. 2017-09-01T06:12:52Z 2017-09-01T06:12:52Z 2017-09-01T06:12:52Z 2017 conference output P.
