abstract = "Macroscopic testing of the hydrogen embrittlement (HE) resistivity of ultra and advanced high-strength steels is still a difficult task. Different testing procedures are recommended in literature, such as the slow strain rate (SSR) test, the constant load (CL) test, or the incremental step load (ISL) test. Nevertheless, a direct comparison of the results of the different testing procedures is challenging and the influence of the microstructure is not well understood. Therefore, the present work contributes to a deeper understanding of the role of internal hydrogen diffusion and trapping at microstructural defects during SSR testing of notched samples using physical reasonable diffusion-mechanical finite element (FE) simulations. The modeling approach allows a detailed study of the role of macroscopic strength and multiple trapping sites on the local hydrogen accumulation at the notch.",
