Insights Into Paint‐Bake Toughening of Resistance Spot Welds of a 2.0 GPa Warm‐Stamped Medium‐Mn Steel

open access: yessteel research international, EarlyView.
Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

open access: yessteel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Damage Investigation of the Preform Operations for the Production of Rings for Ring Rolling

open access: yessteel research international, EarlyView.
Void evolution during the preforming operations of two industrial ring rolling process routes is investigated by combining metallographic characterization with a two‐scale finite element simulation approach. The results reveal that, despite differing initial void conditions, the preforming operations can be designed to effectively influence void ...

Effect of Mn Content on Microstructure and Properties of Inconel718 Plate Welded Joint

open access: yesTeshugang
The service performance of welded parts is directly impacted by the microstructure of the Inconel718 welded joint; however, there is a lack of comprehensive research on the impact of the Mn element on the microstructure and performance of the welded ...

Experimental and theoretical investigation of longitudinal tunnel lining joints with confining reinforcement

open access: yesStructural Concrete, EarlyView.
Abstract Precast reinforced concrete segmental linings are frequently used in modern tunneling. In these linings, the longitudinal joints typically have a reduced contact cross‐section and thus often govern the design, particularly in tunnels under high hydrostatic pressure or crossing squeezing or swelling ground with correspondingly high ...

Moment‐curvature behavior of continuous reinforced concrete slab strips—Experimental determination and modeling

open access: yesStructural Concrete, EarlyView.
Abstract With the market introduction of new reinforcing materials, such as corrosion‐resistant steel, the effect of their stress–strain relationship on the ductility of reinforced concrete structures needs to be evaluated. Their moment‐curvature behavior significantly influences bending moment redistributions, rotation capacity, and deformation at ...

Fatigue life estimation in welded joints under multiaxial loadings

open access: yesFracture and Structural Integrity, 2009
Welded joints are frequently locations for cracks initiation and propagation that may cause fatigue failure of engineering structures. Biaxial or triaxial stress-strain states are present in the vicinity of welded joints, due to local geometrical ...

Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

open access: yesStructural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

Structural behavior of small square steel tubes reinforced self‐compacting concrete columns under biaxial eccentric loads

open access: yesStructural Concrete, EarlyView.
Abstract In this study, the structural behavior of small square steel tube‐reinforced self‐compacting concrete (SSTR‐SCC) columns is investigated under symmetric and asymmetric biaxial eccentric loads. Twelve specimens were cast and tested under biaxial eccentric loads.
