Phase-field models for fatigue crack growth [PDF]

open access: yesTheoretical and Applied Fracture Mechanics, 2019
We introduce a class of models based on near crack tip degradation of materials that can account for fracture growth under cyclic loads below the Griffith threshold. We incorporate the gradual degradation due to a cyclic load through a flow equation that decreases spatially varying parameters controlling the fracture toughness in the vicinity of the ...

Ensemble of Models for Fatigue Crack Growth Prognostics [PDF]

open access: yesIEEE Access, 2019
Various models of fatigue crack growth in different scenarios have been proposed in the literature. Here, in this paper, we propose a general prognostic framework for tracking crack evolution in equipment undergoing fatigue and predicting the Remaining Useful Life (RUL).

Statistical assessment of multiaxial HCF criteria at the grain scale [PDF]

open access: yes, 2014
Multiaxial high cycle fatigue modeling of materials is an issue that concerns many industrial domains (automotive, aerospace, nuclear, etc.) and in which many progress still remains to be achieved.

Reconstruction of fan blade dynamic loading prior to its fracture

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2022
To maintain the functionality of fan blades, it is important to know the distribution of dynamic stresses in the blade, their amplitude and vibration frequency. Understanding of the dynamic loading pattern will allow us to determine under what conditions

Multi-timescale analysis of fatigue crack growth on interfaces via cohesive-zone models [PDF]

open access: yes, 2014
The paper describes a new non-linear finite-element formulation to analyse fatigue debonding or delamination, along predefined interfaces, which is multi-scale in time. At the small timescale level, cyclic loading and the related oscillating response are

Simulation of Quasi-Static Crack Propagation by Adaptive Finite Element Method

open access: yesMetals, 2021
The finite element method (FEM) is a widely used technique in research, including but not restricted to the growth of cracks in engineering applications.

Modelling the role of non metallic inclusions on the anisotropic fatigue behaviour of forged steel [PDF]

open access: yes, 2011
Forged components are known to show high cyclic and monotonic mechanical properties. This is mainly due to a better compactness and a finer microstructure introduced by the forming process. However, this good mechanical behaviour is sometimes a source of

Design and modeling of selective reinforcements for integral aircraft structures [PDF]

open access: yes, 2007
A numerical simulation is presented in this paper on the performance of crack retarders bonded to integral metallic structures. The work is described in two main parts.
