Using FEM calculations and a new design of permeation testing under tensile loading up to fracture, we revisit the question of hydrogen embrittlement of martensitic steel. More precisely, we explore the impact of mobile and trapped hydrogen on ductile and brittle fractures of martensitic steel using local approach of fracture and a specific analyze of the defect evolution under hydrogen flux (vacancies and dislocations).
