Influence of Oxygen‐Free Atmosphere on Surface Grinding: Process Forces, Residual Stresses, and Surface Quality

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
The study shows that grinding under an oxygen‐free atmosphere reduces grinding forces for certain materials significantly and alters residual stress states. The influence of the atmosphere becomes apparent at higher thermal loads, highlighting the strong coupling between oxygen content, process temperature, and material response during surface grinding.

Effect of Er:YAG Laser Irradiation on the Flexural Fatigue Strength of a 4YSZ Ceramic

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 1, January 2026.
ABSTRACT This study aimed to evaluate the effect of Er:YAG laser surface treatment on the flexural fatigue strength of 4YSZ ceramics, with or without resin cement application. Disk‐shaped zirconia ceramic specimens (Ø = 15 mm, thickness = 1.2 mm of IPS e.max ZirCAD MT BL) were prepared and randomly assigned to 10 groups based on two factors: “surface ...

Stress Corrosion Tests for Prestressing Steels—Part 2: Susceptibility of Quenched and Tempered Wires—Influence of Chromium

open access: yesMaterials and Corrosion, Volume 77, Issue 1, Page 36-45, January 2026.
Cr‐alloyed quenched and tempered prestressing steel wires were found to be as highly susceptible as non‐Cr‐alloyed ones. This finding is in contrast to the known literature. A newly developed and reproducible method for assessing susceptibility to hydrogen‐induced stress corrosion cracking was used.

Rheological Characterization of Low and High‐Solids‐Loaded Suspensions Using Capillary Rheometry

open access: yesPropellants, Explosives, Pyrotechnics, Volume 51, Issue 1, Page 144-156, January 2026.
ABSTRACT Controlled extrusion of viscous liquids with suspended solids depends critically on rheology. The rheology of a binder (9:1 mass ratio of cellulose acetate butyrate (CAB) to triacetin with a 55 wt.% diethyl ketone balance) loaded with dilute (0–15 wt.%) and concentrated (≥50 wt.%) granulated sugar loadings from three particle size ...

Research on Prediction of Remaining Useful Life of Wheel Machining Tool Based on EMD–PSO–LSTM Model

open access: yesThe Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
A novel EMD–PSO–LSTM framework is proposed for precise tool remaining useful life prediction in wheel machining, where empirical mode decomposition (EMD) extracts multi‐scale features from sensor data, and particle swarm optimization (PSO) enhances long short‐term memory (LSTM) hyperparameters, achieving superior robustness and accuracy.
