Stresses Evaluation by Transmission Energy Dispersive X-Ray Diffraction Using Industrial Radiography Equipment

Abstract:

X-rays transmission stress analysis was tested on a 2mm thick steel sheet using energy dispersive X-rays diffraction (EDXD) and an industrial radiography equipment as X-ray source. A complex state of residual stresses was created in the sheet before the test and modified during the experiment by the way of a in-situ tensile test. In the diffracted beam spectrum, the energy peak displacement was related to macroscopic stresses using the elementary Mohr’s circle formalism for plane stress analysis. The change in the stresses thus analyzed is compared with the applied stress.
