Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 6, Page 2649-2668, June 2025.ABSTRACT The paper at hand presents a new numerical model based on experimental investigations of the low‐cycle fatigue behavior of the high‐strength aluminum alloy EN AW‐7020 T6. The developed plastic damage model is based on J2 plasticity with Charboche‐type mixed kinematic hardening blended with a suitable isotropic hardening.

Advanced Engineering Materials, Volume 27, Issue 8, April 2025.A novel metadata schema is introduced to address the sparsity of microstructure‐sensitive mechanical data. The design follows the material modeling workflow, as each run results in the definition of unique data objects. The schema includes categorical elements to ensure findability, accessibility, interoperability, and reusability (FAIR). This approach

Fatigue Design Curves for Industrial Applications: A Review
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 3, Page 1001-1021, March 2025.ABSTRACT In the present paper, a review on the design curves for safe–life fatigue design is provided. The methodologies available in the literature for the assessment of the strain–life and stress–life design curves have been analyzed, focusing also on the industrial practice for the design of critical components.

Ratcheting Simulation in a Titanium-Steel Bimetallic Plate Based on the Chaboche Hardening Model [PDF]
Acta Mechanica et Automatica, 2016 Abstract The paper presents the results of fatigue loading simulation applied to bimetallic model using the Chaboche kinematic hardening rule. Three cases of simulations were performed: (i) without residual stresses; (ii) considering residual stresses and (iii) considering asymmetrical geometry of bimetal, i.e.
