Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]

MATEC Web of Conferences, 2018
Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

Crack Front Segmentation and Facet Coarsening in Mixed-Mode Fracture [PDF]

, 2015
A planar crack generically segments into an array of "daughter cracks" shaped as tilted facets when loaded with both a tensile stress normal to the crack plane (mode I) and a shear stress parallel to the crack front (mode III).

INFLUENCE OF MATERIAL PARAMETER MISMATCH ON CRACK PROPAGATION IN COMPOSITE LAMINATES

Jixie qiangdu, 2022
The propagation path of cracks perpendicular to the interface of composite laminates usually takes many forms. By analyzing the stress field of crack tip during crack propagation, the driving force of crack tip is determined, in this way, the crack ...

Continuum field description of crack propagation

, 2000
We develop continuum field model for crack propagation in brittle amorphous solids. The model is represented by equations for elastic displacements combined with the order parameter equation which accounts for the dynamics of defects. This model captures

A three-dimensional multiscale model of intergranular hydrogen-assisted cracking [PDF]

, 2010
We present a three-dimensional model of intergranular hydrogen-embrittlement (HE) that accounts for: (i) the degradation of grain-boundary strength that arises from hydrogen coverage; (ii) grain-boundary diffusion of hydrogen; and (iii) a continuum model

Thermal fatigue crack behavior of SiCp/A356 composites prepared by stirring casting

Results in Physics, 2017
The thermal fatigue crack initiation and propagation behavior of SiCp/A356 composites which is produced by stirring casting were studied. Specimens with a V-shaped notch were used in the thermal fatigue experiment.

Branching mechanism of intergranular crack propagation in three dimensions

, 2005
We investigate the process of slow intergranular crack propagation by the finite element method model, and show that branching is induced by partial arresting of crack front owing to the geometrical randomness of grain boundaries. A possible scenario for

Crack propagation in thin shells by explicit dynamics solid-shell models [PDF]

, 2013
A computational technique for the simulation of crack propagation due to cutting in thin structures is proposed. The implementation of elastoplastic solid-shell elements in an explicit framework is discussed.
