A modified cyclic cohesive zone model (CCZM) is developed for low-cycle fatigue crack
initiation prediction for subsea pipelines. The traction and separation law in the model is …

Hydrogen induced failure under uniaxial tension is simulated in a duplex stainless steel
considering microstructural feature of the material. There are three key ingredients in the …

Hydrogen embrittlement is a classical problem in bulk materials while it is rather untouched
for advanced materials such as micro-architectured materials. This can be a barrier to …

Compact-tension (CT) specimens made of low alloy 30CrMo steels were hydrogen-charged,
and then subjected to the fracture toughness test. The experimental results revealed that the …

To study the discrete crack growth of heterogeneous materials, a dual-scale discrete fracture
calculation method is proposed in this paper. An equivalent cohesive energy criterion is …

This study focuses on the effect of hydrogen on fracture toughness of AISI 1020 and API 5L
X80 steels using experimental measurement technique and numeric simulation. Hydrogen …

This work addresses a hydrogen–induced cracking methodology incorporating the fully
coupled problems of elastoplastic deformation and hydrogen transport within cohesive …

Carbon steel is one of the most commonly used engineering materials. However, the
mechanical properties of steel deteriorates due to exposure to harsh environments like …

Hydrogen-induced fractures usually occur in low alloy steel under the influences of stress
concentration and high-pressure hydrogen gas. The purpose of this study was to predict the …

Crack extensions in sub-sized side-grooved bend specimens of AM steels are examined
with changing cohesive parameters. Two-dimensional FE analyses are first conducted to …
