Stress-strain properties of hss steel welded joint heterogeneous structure: experimental and numerical evaluation [Elektronski vir]Tomerlin, Damir ...Welded joints show significant heterogeneity as they are composed of base metal, heat affected zone and weld metal. Heat Affected Zone (HAZ) is further divided into characteristic segments. All the ... listed zones of the welded joints have certain microstructural differences and consequent differences in mechanical properties. Mechanical experimental examination and determination of stress-strain characteristics of such heterogeneous welded joints structure, especially in certain segments of the HAZ is very difficult. The classical approach to stress-strain testing using standard tensile specimens have only limited applicability, as even the subsize tensile specimens are difficult to position within the narrow HAZ segments. Difficulties in such experimental measurements and the possibility of testing the welded joints in full scope are the motivation for use of alternative experimental methods. The paper considers double-V butt joint made of High Strength Steel (HSS), welded with filler metal having approximately the same mechanical properties as base metal. Experimental work is focused on stress-strain properties determination with Mini tensile Specimens (MTS) used to determine the properties along the transverse weld line. The aim of the paper is the development of an appropriate computer model based on sufficient experimental data, describing the complete welded joint and its specific zones. The evolution of such model is done, starting with a simple model and refining it to a complex, fully segmented welded joint model. This final welded joint model is implemented into ASTM E8 large size specimen, oriented transverse to the welded joint, and covering all specific zones of the welded joint. Material behaviour is simulated using the ductile damage initiation criterion. Tensile test simulation results show good correlation between experimental data and numerical evaluation. Simulated tensile specimen fracture location matches the HAZ segment with decreased strength values, most prone to failure. The paper demonstrates the possibility of experimental determination of stress-strain mechanical properties throughout the heterogeneous welded joint regions, using the MTS specimens. These results can then be used to create a fully segmented welded joint model for tensile testing, or some similar applications.Vrsta gradiva - prispevek na konferenci ; neleposlovje za odrasleLeto - 2023Jezik - angleškiCOBISS.SI-ID - 167301891
