PhD Position in Department of Structural Engineering
The Toppforsk project FractAl deals with microstructure-based modelling of ductile fracture in aluminium alloys. The project started in August 2016 with 5 years duration. In the design of aluminium structures against failure, the material’s strength and ductility are important factors. To design lightweight structures it is often necessary to use high strength aluminium alloys, while taking advantage of ductility in full. For aluminium alloys, increased strength often comes at the expense of ductility of the material. This can increase the risk of structural failure. Therefore, it is important to have good models for ductility of aluminium alloys under different load situations. In FractAl we will develop and validate a new microstructure-based modelling framework for ductile fracture in aluminium alloys. It involves modelling and simulation at multiple scales and customized laboratory experiments. Besides building a basic understanding of ductile fracture in aluminium alloys, the modelling framework enables designers and engineers to select the most suitable aluminium alloy for a given structure with less time-consuming and costly mechanical tests. The framework can also be used to tailor alloys with ideal strength and ductility of a given structure. This could pave the way for a completely new way to design aluminium structures.
The topic of the vacant PhD position is microstructure-based modelling and simulation of dynamic fracture in aluminium alloys based on nanostructure models for precipitation, yield strength and work hardening, crystal plasticity models for plastic anisotropy and unit cell models for damage evolution and failure. Special emphasis is put on describing the influence of stress state and loading path on the ductility of aluminium alloys to be used in protective structures. By protective structures we mean energy absorbing components used to protect against accidental loads such as explosions, impacts and collisions. It is important to realize that the protective structure is the last layer of defence against a threat when all other protective measures have failed. It is thus of utmost importance that such structures are designed and validated on a sound theoretical and experimental basis. To do so, accurate, efficient and robust constitutive models and solution techniques used in a multi-scale modelling framework are required.
The successful applicants are motivated and ambitious students with excellent grades and background in materials mechanics, experimental mechanics, non-linear finite element methods, impact mechanics and similar. The PhD applicant is expected to carry out both theoretical, numerical and experimental work. The research work will rely on cooperation with our regular laboratory staff, interacting with several people on various levels; participate in team work, as well as initiating and running experiments. The applicant should be fluent in English (spoken and written), familiar with giving presentations and lectures in English, and preferably speak Norwegian.
