A self-heating test under cyclic loading is carried out on a seam weld joint. During the test, displacement and temperature fields of the specimen are measured by Stereo Digital Image Correlation (SDIC) and Infra-red (IR), respectively. Then a suitable numerical strategy is proposed to identify a given thermal source model. Thus, a correlation between the change of the seam weld dissipative source and the expected mean fatigue strength of the assembly is successfully recovered. %G English %L hal-01137767 %U https://hal.science/hal-01137767 %~ UNIV-BREST %~ ENSTA-BRETAGNE %~ ENSTA-BRETAGNE-LBMS %~ ENIB %~ ENSTA-BRETAGNE-MECA
