Abstract
The present paper reports the results of experimental tensile tests, geometrical measurements and Vickers hardness tests in order to characterize the deformation process and the material failure of a HT780 butt welded joint specimens. In addition, the distribution of the strain fields on the surface of the samples is obtained by means of the digital image correlation technique. Furthermore, the relationship between the local stress-strain behavior and hardness is discussed from the results.
