For the HyTROS project awarded by the Dutch Research Council (NWO) on hydrogen transport, offshore and storage, a PhD position for the period is available in the context of modelling hydrogen embrittlement of pipeline steels. In this project, the University of Groningen, in collaboration with TU Delft, will unravel the fundamental origin of hydrogen-induced fatigue crack growth by a multi-scale modelling approach. The focus of this position is the atomistic modelling of crack propagation in steels in presence of hydrogen and inhibiting gases (e.g. ppm oxygen), as well as scale bridging from atomistic to microscale crystal plasticity simulations. This includes the development of a quantum-accurate interatomic potential to study crack propagation and hydrogen embrittlement in pipeline steels.
It is well known that hydrogen enhances the fatigue crack growth (HFCG) rate. The physical mechanism at the origin of this phenomenon is however unknown. Detailed understanding of HFCG would allow for optimal usage of (existing) pipelines for hydrogen transport. Furthermore, recent investigations have revealed that mixing small ppm oxygen/inhibiting gases could mitigate HFCG, yet the reason for this is not understood. This project aims at providing a mechanistic model for HFCG and unraveling the mechanism behind gaseous inhibition of HFCG.
The successful candidate will be co-supervised by dr. Francesco Maresca from the Computational Mechanical and Materials Engineering (CMME) unit of the Engineering and Technology institute Groningen (ENTEG) and by Prof. Erik van der Giessen from the Micromechanics unit of the Zernike Institute for Advanced Materials.
