Unveiling the mechanical response and accommodation mechanism of pre-rolled AZ31 magnesium alloy under high-speed impact loading

Journal of Magnesium and Alloys, 2022
Split Hopkinson pressure bar (SHPB) tests were conducted on pre-rolled AZ31 magnesium alloy at 150–350 ℃ with strain rates of 2150s-1, 3430s-1 and 4160s-1.

A shear brittleness index for rock joints and its application in direct shear failure analysis

Results in Engineering
The brittle shear failure of rock mass structural planes is an important cause of structure-controlled rockburst, which severely threatens the safety construction of deep rock engineering.

Superconductivity in Compression-Shear Deformed Diamond

Physical Review Letters, 2020
Diamond is a prototypical ultrawide band gap semiconductor, but turns into a superconductor with a critical temperature T_{c}≈4  K near 3% boron doping [E. A. Ekimov et al., Nature (London) 428, 542 (2004)NATUAS0028-083610.1038/nature02449]. Here we unveil a surprising new route to superconductivity in undoped diamond by compression-shear deformation ...

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

Arthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Shear dominated deformation with curved beaks in folding–shearing

The International Journal of Advanced Manufacturing Technology
Abstract The deep drawing process in the automotive industry generates up to 45% material waste. To address this issue, the folding–shearing process was developed as a drop-in solution, enabling the formation of parts in pure shear with minimal thickness variation.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
