Doctoral Student in Material and Structural Mechanics (Solid Mechanics, Additive Manufacturing, Nuclear Applications)

Project Overview: The Department of Engineering Mechanics at KTH Royal Institute of Technology invites applications for a fully funded PhD position in Material and Structural Mechanics, with a focus on solid mechanics and additive manufacturing for nuclear reactor applications. The research aims to develop advanced models for predicting the fatigue life of additively manufactured steel in nuclear reactor water environments, addressing corrosion fatigue under cyclic loading in pressurized, high-temperature water. The project integrates material modeling (crystal plasticity, phase-field methods, finite element analysis) with advanced experimental work in simulated nuclear environments, linking microstructure and manufacturing processes to material lifetime predictions. Research Environment: The position is part of a newly established, interdisciplinary research environment funded by the Swedish Research Council, involving KTH, Karlstad University, Lund University, and the Swedish nuclear power industry. The team includes senior professors, junior researchers, and several PhD students, fostering collaboration between solid mechanics and materials science with strong industry ties. The overall goal is to support the long-term operation of nuclear power plants by establishing additive manufacturing as a viable alternative for critical steel components. Supervision: The doctoral student will be supervised by Dr. Mustafa Subasic and Professor Jonas Faleskog (KTH), and Professor Pavel Krakhmalev (Karlstad University), providing a broad academic and industrial perspective. Funding and Employment: The position offers a monthly salary according to KTH's doctoral student salary agreement and is fully funded for up to four years. Employment is full-time and includes employee benefits. The initial contract is for one year, with possible renewals up to a total of four years, and may include up to 20% departmental duties. Eligibility: Applicants must hold a second cycle degree (master's or equivalent) or have completed at least 240 higher education credits (with at least 60 at the second-cycle level). Proficiency in English equivalent to English B/6 is required. Selection is based on academic qualifications, ability to work independently and collaboratively, professional approach, and analytical skills. Personal suitability is highly valued. Security clearance may be required for certain positions. Application Process: Applications must be submitted via KTH's recruitment system by 2026-04-16. Required documents include a CV, application letter (max 2 pages), certified copies of diplomas and grades, proof of language proficiency, and representative publications or technical reports. Translations into English or Swedish are required if originals are in other languages.
