Corrosion fatigue of a superduplex stainless steel weldment [PDF]

, 2004
Superduplex stainless steels have superior mechanical and corrosion properties compared to austenitic stainless steels such as the grade 300 series. This is a result of a microstructure consisting of roughly equal percentages of austenite (y) and ferrite

Fatigue crack growth in thin notched woven glass composites under tensile loading. Part II: modelling [PDF]

, 2011
Fatigue propagation of a through-the-thickness crack in thin woven glass laminates is difficult to model when using homogeneous material assumption. Crack growth depends on both the fatigue behaviour of the fibres and of the matrix, these two phenomena ...

Numerical simulation of coupling characteristics between fracture propagation and internal decompression of CO2 pipelines

You-qi chuyun
Objective Pipelines serve as the primary transportation means for Carbon Capture, Utilization and Storage (CCUS) technology, so it is vital to study their dynamic fracture propagation laws.

Numerical simulation of microstructually short crack propagation in creep.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1987
A numerical simulation model of the propagation of a microstructually short crack in monotonic creep was proposed. In the model, the distribution of the crack propagation rate caused by the microstructual inhomogeneity was expressed by means of some random variables showing the grain boundary length and the crack propagation rates at the grain boundary

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

A novel crack propagation rate model based on a two-parameter approach for electron beam welded joint of nickel-based superalloys

Philosophical Magazine Letters
Fatigue crack propagation tests were carried out on Nimonic 80A electron beam welded joints with different stress ratio using standard CT specimens. The crack propagation rate was characterised using the ‘[Formula: see text]’ method, the ‘[Formula: see ...

The cohesive frictional crack model applied to the analysis of the dam-foundation joint [PDF]

, 2010
The mechanical behaviour of dam-foundation joints plays a key role in concrete dam engineering since it is the weakest part of the structure and therefore the evolutionary crack process occurring along this joint determines the global load-bearing ...

The effect of inclusions and pores on creep crack propagation of linear friction welded joints of GH4169 superalloy

Journal of Materials Research and Technology
Superalloy has become the key material in components of blisks for aero-engines produced by linear friction welding. However, during the long-term service of the blisks, stress rupture occurs on the blisk under long-term creep.
