In-situ interrupted tensile tests combined with Digital Image Correlation (DIC) were performed on S960 hot rolled steel to identify damage initiation on the surface of the sample. Shear bands and damage initiation and evolution in the microstructure were observed during the test. It was found that shear bands are generated on the surface as plastic deformation occurs. Void nucleation was found to be initiated where a large plastic deformation gradient is observed.
