Hydrogen (H), emerging as a sustainable and promising clean energy source, holds
significant potential for transitioning towards a H-based economy, offering a cleaner …

Hydrogen is considered a clean and efficient energy carrier crucial for sha** the net-zero
future. Large-scale production, transportation, storage, and use of green hydrogen are …

The detrimental effect of hydrogen on metals which manifests itself as a transition from a
ductile to a brittle failure mode is, for the first time, incorporated into a unified continuum …

Damage and fracture can be induced not only by mechanical loading but also due to
chemical interactions within a solid. On one hand, species concentration may embrittle or …

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 …

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 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 …

Hydrogen energy is a candidate of the “ultimate energy”. However, the quantified evaluation
of hydrogen embrittlement phenomenon remains to be a challenging topic. This paper …

We combine welding process modelling with deformation–diffusion–fracture (embrittlement)
simulations to predict failures in hydrogen transport pipelines. The focus is on the structural …

A new simulation strategy to model hydrogen embrittlement based on a multi-field finite
element using displacements, pressure, volume variation, nonlocal damage variables and …
