Non‐destructive orientation tracking of individual β‐Sn grains in die‐attach solder joints

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 617-631, May 2026.
This study introduces inclined scanning three‐dimensional X‐ray diffraction microscopy (i‐S3DXRD) that enables three‐dimensional orientation mapping of planar polycrystalline materials, revealing the thermal fatigue mechanism of Pb‐free solder joints.Understanding the failure mechanisms of Pb‐free solder joints during thermal cycling is a critical ...

Numerical Modeling of Hydrogen‐Assisted Cracking With Phase Field Regularized Cohesive Zone Model and Penalty‐Based Moving Hydrogen Boundary Condition

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1824-1844, May 2026.
ABSTRACT The degradation of metallic materials due to hydrogen embrittlement (HE) poses critical challenges for structural reliability. Phase‐field models offer an energy‐based approach that does not require predefined crack paths and automatically determines crack initiation, growth, and coalescence.

How Can Technology Improve Acetabular and Pelvic Fractures Management in the Operating Room? A Systematic Review

Orthopaedic Surgery, Volume 18, Issue 5, Page 915-931, May 2026.
New technologies are very attractive and are a promising help in pelvic and acetabular fractures surgery. Their results demonstrated greater surgical accuracy without increasing complications and need to be improved before being included in routine care.

Limited contribution by non‐volant small mammals to regeneration in ironstone rocky outcrops

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Animal‐mediated seed dispersal contributes substantially to natural regeneration in degraded areas. However, the role of seed dispersal by non‐volant small mammals (NVSM), mainly marsupials and rodents, in contributing to regeneration remains underexplored, especially in mountaintop, open‐canopy ecosystems.

Phase‐Field Fracture Simulation of Pressurized Concrete Microstructure

International Journal for Numerical Methods in Engineering, Volume 127, Issue 8, 30 April 2026.
ABSTRACT Pressurized cracks in concrete have a significant impact on the safety and durability of concrete structures. The peak strength of concrete is reduced in the presence of pressurized cracks. However, conducting pressure‐coupled strength evaluation experiments requires extensive effort, and simulation tools can complement the time‐consuming and ...
