Fatigue of AM TiAl6V4: Probabilistic Modelling of the Size Influence as a Transfer Method From Test Specimen to Part

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 4586-4606, November 2026.
ABSTRACT This paper investigates the fatigue behavior of additively manufactured TiAl6V4 by comparing two specimen geometries with different highly stressed volumes. A fracture mechanical approach based on the El‐Haddad–Smith–Topper model is combined with defect analysis through X‐ray computed tomography.

Assessment of local multiaxial stresses on a cast aluminium truck wheel under complex service loading and fatigue life evaluation

, 2022
S.42.1-42.3The assessment of multiaxial stress states is already a very difficult subject for constant amplitude loading. If the stresses occur additionally at random, the assessment procedure becomes even more complex, because the design engineer is ...

Critical volume approach in multiaxial fatigue assessment of notched specimens [PDF]

openEngineers are facing the problem of fatigue of materials since more than one century. This mechanical phenomenon is particularly challenging because it can lead to the catastrophic failure of mechanical parts without any visible warning signs.

Continuous Stiffness Graded Metal–Ceramic Femoral Stems: UMAT‐Based Design and Finite Element Assessment

Advanced Engineering Materials, Volume 28, Issue 18, 23 September 2026.
Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Fatigue Assessment of Rib–Deck Welded Joints in Orthotropic Steel Bridge Decks Under Traffic Loading

CivilEng
Rib–deck (RD) welded joints in orthotropic steel bridge decks are prone to different fatigue crack mechanisms. Standard fatigue design methods are inadequate for some of these mechanisms under multiaxial non-proportional loading conditions.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
