This work presents a novel strategy to model the coexistence of HELP & HEDE mechanisms.
The proposed method accounts for ductile and brittle damage with a competitive fracture …

This paper proposes a definition of a Hydrogen Embrittlement Index for assessing structural
components made by a martensitic advanced high-strength steel. A material model …

Regarding hydrogen embrittlement (HE) in the mixtures of hydrogen and inert gas, the
results were understood mainly based on the partial hydrogen gas pressure. On the other …

This paper presents a simulation method for combined ductile–brittle fracture of small punch
(SP) test in hydrogen and application to test data of API X70 steel. For ductile fracture …

In this paper, we propose a numerical methodology to predict the effect of hydrogen
concentration on fracture toughness by using small punch (SP) test data in hydrogen. The …

There is a consensus for transitioning to clean energy sources to meet the world's energy
demands. Hydrogen is a candidate to supply green energy. However, hydrogen …

This paper proposes a numerical method to predict fracture resistance of pre-strained
materials, which is further applied to predict fracture resistance of irradiation-embrittled …

This paper quantifies the effect of temperature (ranging from room temperature (RT) to-90°
C) on fracture toughness for hydrogen-embrittled API X52 by combining small punch (SP) …

In engineering applications, the phenomenon of cracking is often accompanied by a
coupled multiphysics effect. Peridynamics (PD) is an effective approach for solving cracking …

The lightweight nature and exceptional temperature resistance of titanium (Ti) render it a
highly favored material for spacecraft applications. However, Ti is susceptible to various …
