Calculation and Experimental Verification of Residual Stresses in Riveted Joints Used in an Airframe

This paper presents diffraction measurements of residual stresses around the rivet, formed during the riveting process. The measurements were made with the XSTRESS-3000 diffractometer, manufactured by Stresstech Oy. The measurements were carried out on specimens made of bare sheet 2024-T3 alloy, (standard AMS-QQ-250 / 4). The measurement results were compared with the FEM simulation results.

The work was performed under the EUREKA IMPERIA project E! 3496.
