Experimental study of cyclic creep and high-cycle fatigue of welded joints of St3 steel by the DIC technique
- 1. Institute of Strength Physics and Materials Science SB RAS, Tomsk, 634055 (Russian Federation)
Description
In the paper the mechanisms of plastic deformation and fracture of welded joints of steel St3 were investigated at high-cycle fatigue and cyclic creep by the digital image correlation (DIC) technique. The evolution of strain rate is studied for the following regions: base metal, HAZ, and fusion zone. This strain rate evolution can be considered as a mechanical response of material. Three stages of deformation evolution are shown: deformation hardening (I), fatigue crack initiation (II), and the last stage is related to main crack (III). Two criteria are offered to evaluate the current mechanical state of welded joints
