The Department of Structural Engineering at the Norwegian University of Science and Technology (NTNU) announces two fully funded PhD positions in the field of micromechanics-based modelling of ductile failure in high-strength aluminium alloys. These positions are part of a collaborative research project involving the Structural Impact Laboratory (SIMLab) and Nanomechanics research groups, focusing on fundamental fracture mechanisms in age-hardenable aluminium alloys used in modern electric vehicles. Aluminium alloys are critical for lightweight automotive design, offering a unique balance of strength and ductility. However, optimizing these properties remains a challenge due to microstructural features such as precipitate-free zones (PFZs) and grain-boundary precipitates, which can lead to strain localization and void nucleation, ultimately compromising ductility. The project aims to address the competition between transgranular and intergranular fracture in these alloys, a question central to improving crashworthiness and structural integrity in electric vehicle components. PhD position 1 will investigate intergranular fracture mechanisms, emphasizing the role of PFZs and boundary precipitates through advanced experimental characterization and modelling. PhD position 2 will focus on transgranular fracture, utilizing physics-based computational modelling, crystal-plasticity finite-element (CPFE) simulations, and microstructure-resolved models to capture ductile damage initiation and crack evolution in polycrystalline materials. As a PhD candidate, you will develop multiscale modelling frameworks, combine computational and experimental approaches, and contribute to materials design and performance prediction for crash-relevant loading conditions. The research environment is highly international and interdisciplinary, offering opportunities to publish in peer-reviewed journals, present at international conferences, and participate in group activities such as mentoring MSc students. Applicants must have a relevant background in solid mechanics, a master's degree or equivalent, strong academic performance (B or better on NTNU's scale), and fluency in English. Preferred skills include constitutive modelling, non-linear finite element methods, computational micromechanics, experience with aluminium alloys, programming (Python, Fortran), and experimental work. Personal qualities such as motivation, independence, curiosity, and strong communication skills are valued. The positions offer a gross annual salary of NOK 550,800, favourable pension terms, and employee benefits. The employment period is three years, with the requirement to gain admission to the PhD programme in Engineering within three months of the contract start date. NTNU values diversity and encourages applications from candidates of all backgrounds. Applications must be submitted electronically via Jobbnorge.no by March 30, 2026. Required documents include transcripts, diplomas, CV, motivation letter, publications, and referee contact information.

The Norwegian University of Science and Technology (NTNU) invites applications for a 3-year postdoctoral fellowship in Microstructure-Informed Modelling of Fracture in Cast Aluminium Alloys. This position is based at the Department of Structural Engineering and is part of the CastAl project, a collaborative research initiative with Hydro Aluminium and Honda. The project focuses on understanding the stochastic fracture behaviour of high-pressure die-cast (HPDC) aluminium alloys, aiming to develop advanced virtual modelling frameworks that incorporate microstructural data and defect characterization. The successful candidate will work at the intersection of experiments, computational modelling, and data-driven methods. Research activities include advanced microstructural characterization using SEM and X-ray computed tomography, finite element modelling, and the application of machine learning techniques to analyze defect populations and their influence on fracture behaviour. The project also involves reconstructing three-dimensional pore structures from radiography and linking defect characteristics to mechanical testing results. The position offers the opportunity to join the internationally recognized SIMLab research group, participate in teaching and mentoring activities, and engage in international collaborations. Career guidance and a mentor programme are provided, along with favorable terms in the Norwegian Public Service Pension Fund and free basic Norwegian language training. The position is full-time, with a gross annual salary starting from NOK 604,900 before tax, and includes comprehensive employee benefits. Applicants must hold a PhD in solid mechanics, computational mechanics, or a closely related field, with a strong academic record. Candidates nearing completion of their doctorate may apply if they can document thesis submission or a confirmed defense date. Strong communication skills in English are required, and knowledge of Norwegian or another Scandinavian language is advantageous. Preferred qualifications include expertise in non-linear finite element methods, materials mechanics, fracture mechanics, machine learning, and experience with industry-oriented research projects. To apply, submit your application electronically via Jobbnorge.no, including your CV, diplomas, certificates, doctoral thesis (or draft), up to three academic works, recommendation letters, and contact information for three referees. If your education was completed abroad, provide documentation of its scope and quality. The application deadline is 25 April 2026. For further information, contact Associate Professor Lars Edvard Blystad Dæhli at [email protected]. NTNU is committed to diversity and equality in its workforce and encourages applications from all qualified candidates, regardless of gender, background, or career breaks. The university offers a vibrant research environment in Trondheim, a city known for its rich cultural scene, excellent quality of life, and outstanding opportunities for education and family life.
