MARIE CURIE GRANT AGREEMENT NUMBER860104
This PhD is funded by the Marie Curie program of the European Union through the Innovative Training Network GW4SHM on Guided Waves for Structural Health Monitoring
Current efforts in non-destructive evaluation research are focusing on the development of more quantitative inspection methods and exploitation of automation to eliminate time-consuming inspection. Ultrasonic guided wave tomography (GWT) has become an innovative technique to quantify material changes in thin-walled structures such as corrosion in metallic pipes. However, there has been little focus on applying this approach to anisotropic waveguides. The aim of this project is to investigate the performance of GWT on corrosion quantification in pipe bends and on the evaluation of stiffness reduction in composite materials. This requires developing advanced numerical algorithms consisting of:
- a forward solution for describing guided waves in anisotropic media
- an inverse solution for the reconstruction of waveguide parameters
- optimization procedures to link inversion parameters with monitored structural parameters.
Finite element simulations to model different types of damage are required to generate the input data for the tomography, with an aim to verify the detection, localization and sizing capabilities of the algorithm. To improve the fidelity and assess the accuracy of the modelling results, experimental validations on selected artificial and real damages in plates and pipes will be carried out.
The PhD student will be working at the Mechanics of Fluids and Structure Research Group (sub-unit NDE), which has a range of experimental facilities and commercial software tools to carry out this project. The PhD program includes study courses, teaching for one semester, modelling and experiments on doctoral research topics, industrial ultrasonic measurements at the local power plant Enefit Energiatootmine AS, and international collaboration assignments to TNO and CEA-LIST.
The call is open for candidates holding a master’s degree in applied mathematics, physics, mechanical engineering or equivalent. A high level of interest and motivation towards and deep understanding of computational mechanics and ultrasonics are required. A suitable background in applied or computational dynamics or related disciplines is also necessary. It is advantageous when candidates have previous experience in modelling of ultrasonic wave propagation and testing.
The salary will be in the region of €3196 (brutto) per month, the exact salary will be confirmed upon appointment. In addition to this, a Marie Sklodowska-Curie Early Stage Researcher may also have a family allowance of €500 a month, dependent on individual circumstances.
Please note that due to the current situation with the COVID-19 only the candidates from the Schengen Member States and EU can apply. Please combine your CV, motivation letter and the certificates/diplomas in one PDF file and send your application with the subject “ESR11” to Dr. Madis Ratassepp at email@example.com.
