A Surrogate Model for Stability Assessment of Two‐Layered Cohesive Slopes

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 10, Page 4142-4163, July 2026.
ABSTRACT This paper introduces a novel surrogate model for rapid stability evaluation of two‐layered cohesive slopes under undrained conditions. The model eliminates the need for iterative calculations and slip surface searches, allowing for fast and accurate stability assessments without reliance on advanced numerical tools. The formulation is derived

Using Multiple Regression Models and Methods to Estimate Fatigue‐Life Distributions and Construct Constant‐Life Diagrams

Applied Stochastic Models in Business and Industry, Volume 42, Issue 2, March/April 2026.
ABSTRACT Fatigue is the most common reliability failure mechanism and has been studied widely since the 19th century. Material specimens are used in laboratory experiments to obtain fatigue test data. An S‐N curve is used to depict the relationship between the stress (or strain) S$$ S $$ and the number of cycles to failure N$$ N $$. Statistical methods

Effect of long-period stacking ordered structure on very high cycle fatigue properties of Mg-Gd-Y-Zn-Zr alloys

Journal of Magnesium and Alloys, 2023
Magnesium alloys with a long-period stacking ordered (LPSO) structure usually possess excellent static strength, but their fatigue behaviors are poorly understood. This work presents the effect of the LPSO structure on the crack behaviors of Mg alloys in

Carbon‐Driven Enhancement in Zinc Hexacyanoferrate Composites: A Ball‐Milling Approach for High‐Performance Zn‐Ion Batteries

ChemElectroChem, Volume 12, Issue 20, October 16, 2025.
Structural modification of ZnHCF cathodes via ball‐milling and carbon addition significantly enhances the electrochemical performance of aqueous zinc‐ion batteries, achieving capacities close to 100 mAh g−1. The synergistic effect of carbon with ZnHCF preserves the crystalline structure and facilitates phase transitions, greatly improving the cathode's

Influences on the Fatigue Strength of Laser‐Welded High‐Purity Copper Connections

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 10, Page 4148-4160, October 2025.
ABSTRACT Due to their excellent conducting properties, components made of high‐purity copper are increasingly being used in the field of electrified applications. In particular for components with welded joints made of high‐purity copper, there is still no computational basis for evaluating the fatigue strength of these joints.
