The current paper presents a machine learning method based on artificial neural network
(ANN) model for the determination of ductile fracture properties of 16MND5 bainitic forging …

Sulfate reducing bacteria (SRB) are widely present in oil and gas industry, causing pitting
corrosion on pipeline steel. Stress corrosion cracking (SCC) often occurs in the presence of …

The finite element method (FEM) based on the Gurson–Tvergaard–Needleman (GTN)
model was used to investigate the ductile crack growth behaviors at different weld joint …

Abstract Compact-Tension-Shear (CTS) specimen with its loading device has been widely
used in mixed-mode I&II fatigue crack growth (FCG) experiments. To accurately describe the …

Accurately clarifying the influence of cracks on the mechanical behaviors of unidirectional
fiber-reinforced composites (UD FRCs) is of great significance for the structural integrity …

The gap test is a new type of fracture test developed in 2020, in which the end supports of a
notched beam are installed with gaps that close only after the elasto-plastic pads next to …

Bridging the gap between small-scale laboratory specimens and engineering full size
engineering structures plays a critical role in integrity assessment of reactor pressure …

Recent optimum fitting of the data from eleven different types of distinctive fracture tests of
quasibrittle materials, including the gap tests and the size effect tests, revealed that the crack …

In the integrity assessment of natural gas pipelines, it is critical to determine the impacts of
variable wall thickness and misalignment on the fracture of welded joints. In this study …

In the study, a methodology is proposed based on the SENT experiments and crack-tip
constraint theory to determine the tensile strain capacity of a flawed pipe welded girth …
