Apply online The Structures and Safety Section at DTU Civil Engineering is looking for an ambitious, motivated and highly skilled Postdoc fellow eager to dedicate two years to scrutinize the nonlinear performance of offshore platforms exposed to excessive load and harsh environmental conditions. Such a thorough assessment of the structural behavior beyond the linear regime will serve the necessary basis to allow: (i) system identification of the offshore platforms (e.g., estimation of dynamic properties) during their nonlinear response and, (ii) detection of structural damages. Both the nonlinear system identification and the damage detection lie in the core of the current Postdoc scholarship, which is part of a wider project called Innovative Structural Health Monitoring and Risk Informed Integrity Management (InnoSHM), funded by Innovation Fund Denmark. The ultimate goal of InnoSHM is to develop an integrated software solution that will enable detection of the location, size and severity of structural failures and eventually, to translate this information into high quality risk informed decision support. The InnoSHM project is based on simulations. Nonlinear responses, obtained only from a few locations of the offshore platform will form the basis for system identification in order to estimate the evolution of the system properties during the nonlinear response. Hence, advanced numerical models with nonlinear material laws will be developed within the framework of this Postdoc scholarship in order to enable the reliable representation of the nonlinear behavior and the corresponding formation of damages. Subsequently, a damage detection scheme shall be developed to provide a detailed assessment of the damage in the entire structure. The consortium of the InnoSHM project consists of both academic and industrial partners, who will share expertise and join forces in order to fulfill the challenging objectives of the project. Hence, the Postdoc fellow is expected to develop synergy with other members (both academic and industrial) of the InnoSHM in order to secure the smooth and efficient flow of the project activities. The position is available now and will be filled as soon as possible. Responsibilities and qualifications The primary responsibilities and tasks include (but not limited to): Development of nonlinear finite element models of offshore platforms with emphasis on damage modeling Calculation of the linear and nonlinear response of offshore platforms exposed to numerous loading scenarios Identification of nonlinear systems Development of a damage detection method that enables the reliable estimation of the structural damage based on responses obtained from few locations of the offshore platforms Validation of the success rate of the developed identification and damage detection method Support of relevant teaching activities of DTU Civil Engineering Department Supervision and Co-supervision of BSc, MSc projects and PhD projects that are complementary of this PostDoc scholarship You hold a PhD degree (or equivalent). You are highly motivated and research-driven with solid background in Civil or Mechanical Engineering and with background in Structural Health Monitoring, System Identification, Damage Detection, Assessment of Nonlinear Structural Performance or related areas. You have previous experience in the modelling of the nonlinear performance of structural systems via the use of contemporary finite element codes. Preferably, you are familiar with optimization algorithms, vibration measurements, signal processing, machine learning and heuristic methods.
