Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

Advanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

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

steel 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 ...

The Theory of Critical Distances for Predicting the Static Failure of Double‐Lap Bolted Joints With Conventional and Additively Manufactured 316L Stainless Steel Inner Plates

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3831-3853, September 2026.
ABSTRACT This study assesses the accuracy of the theory of critical distances applied in the form of the point method in predicting the static strength of 316L stainless steel double‐lap shear bolted connections under static tensile loading. Single‐ and double‐bolt configurations were tested using inner plates manufactured from conventional material ...

Ediacaran–Cambrian High‐Strain Melt‐Present Deformation of the Archean Charcot Province, East Antarctica

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The assembly of Gondwana involved several Pan‐African orogens, although their extension into ice‐covered Antarctica remains contentious. Particularly problematic is our understanding of the Kuunga orogenic system in East Antarctica, including its eroded architecture and temporal evolution. The remote Charcot Province, at the easternmost extent
