Numerical Investigation of Stress Intensity and Geometry Correction Factors in Welded Longitudinal Stiffener Details

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The safe operation of aging steel railway bridges requires reliable fatigue assessment of welded structural details. Welded longitudinal stiffeners, while not directly loaded, influence structural stiffness and are susceptible to fatigue cracking at weld transitions.

Multiaxial Fatigue Behavior of AA6016 and AA6016 to DX54D SPR Joints: Fracture Mechanisms and Data‐Driven Rupp's Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The fatigue and fracture behavior of self‐piercing rivet (SPR) joints between AA6016 aluminum sheets (1–2 mm) and DX54D steel (0.95 mm) was studied under 90°, 45°, and 0° multiaxial loading. Pure shear (90°) loading produced the highest fatigue strength, whereas multiaxial (45°) loading resulted in reduced performance, with pure tension (0 ...

Simulation of sheet-titanium forming of welded blanks [PDF]

, 2013
The increase in demand for the light and tough drawn-parts causes the growing interest in sheet metal forming of Tailor-Welded Blanks (TWB). Application of such blanks allows for achieving in one operation the drawn-parts characterized by diverse ...

Insights into the structure of grey reef shark aggregation, Carcharhinus amblyrhynchos (Bleeker, 1856), in two distinct channels of the Maldivian archipelago, Indian Ocean

Journal of Fish Biology, EarlyView.
Abstract The grey reef shark Carcharhinus amblyrhynchos is one of the most frequently encountered reef‐associated shark species in the Maldives, yet very little is known about its local size structure or population dynamics. This study provides new insights into two aggregations of C.

The Support Paradox: Explaining (Mis)Matches in Refugee Workplace Support

Journal of Management Studies, EarlyView.
Abstract Recent refugee movements have spurred corporate initiatives, with workplace support proving critical for integration. However, while research on workplace support for refugees remains limited, the broader support literature highlights paradoxical effects – support either benefits or harms recipients depending on how well it matches their needs.

A Critical Review on Friction Stir Spot Welding of Aluminium Alloys: Tool, Mechanical, and Micro-Structural Characteristics

Crystals
Aluminum spot welding is extensively applied in automotive, aerospace, and rail sectors due to its favorable strength-to-weight ratio. While resistance spot welding (RSW) has been the traditional method, its high residual stresses, electrode wear, and ...

Mechanical loss in state-of-the-art amorphous optical coatings

, 2016
We present the results of mechanical characterizations of many different high-quality optical coatings made of ion-beam-sputtered titania-doped tantala and silica, developed originally for interferometric gravitational-wave detectors.
