Research Associate in Ultrasonic inversion for non-destructive evaluation
Posted on May 15, 2019 in Job Opportunities in Acoustics
The rise of high speed computer simulations has provided new opportunities for detecting and quantifying damage within safety-critical components such as jet engines, oil pipes or aeroplane wings. While simulation tools have traditionally been used to produce ultrasonic data for a given geometry and defect, this project on ultrasonic inversion for non-destructive evaluation is about the opposite – given a measured data set, find out by modelling what defect (if there is one!) could have caused this. This has the potential for huge impact within NDE by significantly improving the detection and characterisation of defects.
The successful applicant will be joining a world-renowned research group, within one of the world’s foremost research universities. The NDE group has an excellent record in fundamental and applied research, from the theoretical foundations through to technology transfer to industry. It is well funded by many industrial partners and public grant bodies. The group developed the high speed finite element package Pogo (www.pogo.software) which is becoming increasingly widely used in academia and industry, and the job will make extensive use of this expertise.
Duties and Responsibilities
You will develop algorithms to invert ultrasonic data. In this you will need to
- Develop a thorough understanding of the literature
- Formulate the theory behind suitable inversion techniques for the finite element method with ultrasound
- Implement the theory using suitable computational tools
- Test the algorithms with perfect data initially, then using different models
- Ultimately acquire experimental data, potentially collaborating with our network of industrial partners to obtain real test specimens, and using this to test
- Develop solutions to fix any issues which may arise.
Skills, knowledge and experience
A PhD (or equivalent, or near completion of PhD) in an area pertinent to the research subject i.e. Non-Destructive Evaluation and a first degree (or equivalent) in Mechanical Engineering or Physics.
In addition some background in numerical modelling of waves is essential, ideally with the finite element technique.
Knowledge of inversion techniques and imaging (particularly tomography) is highly essential.
