International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 17, Page 4054-4075, 10 December 2025.ABSTRACT We compare two algorithms to simulate the propagation, arrest, recession, and closure of a planar hydraulic fracture, focusing on their ability to capture the physical processes governing fracture recession and closure. The first algorithm is based on a fixed grid with contact detection during recession, while the second is based on a moving ...

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 12, December 2025.Abstract The elastic modulus profile of a functionally graded material (FGM) is additionally affected by oxygen diffusion. In contrast to earlier work, the reacting material is decreasing in concentration toward the oxygen‐exposed surface, so the rule used to model the elastic modulus is adjusted accordingly.

Crack Propagation in Tooth Root: A Comparison Between Pulsator Test and Running Gears
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 12, Page 5181-5194, December 2025.ABSTRACT Tooth root fatigue fracture is a critical gear failure mode in which the tooth root breaks because of the repetition of bending load. The most widely adopted procedure for evaluating root strength is through pulsator testing. However, this test method does not present gears in meshing conditions. When focusing on the limited‐life region of the

Fatigue life estimation based on LEFM and the study of initial parameters [Elektronisk resurs]
, 2022 The fatigue strength of structural details are usually based on nominal stresses and S-N curves given in the design standards. Using S-N curves to analyse the fatigue strength often gives reliable estimates of the fatigue strength.

Computational Approaches for Crack Propagation in Materials and Structures: Comparison Between Linear Elastic Fracture Mechanics (LEFM) and Peridynamics (PD) Based Strategies [PDF]
In solid mechanics, the defects and imperfections of materials (e.g., cracks, dislocations, etc.) play a key role on the overall mechanical behaviour of the structure despite their localized character.
