Begin your postgraduate research journey on the NSIRC PhD programme with funding and industrial support from Lloyd's Register Foundation (LRF).
The National Structural Integrity Research Centre (NSIRC), TWI Ltd, the University of Huddersfield and LRF have launched a brand new research project, open to UK, EU and international students.
PhD Project: Coded Excitation Methodologies for Ultrasonic Testing Techniques Exhibiting Poor Signal to Noise Performance
- Funding: Available for this PhD Project to students worldwide
- Location: University of Huddersfield, England, and TWI technology Centre, Port Talbot, Wales
Research Proposal for this Industrial PhD
Ultrasonic Testing (UT) is one of the most commonly used inspection techniques that ensures the safe operation of a huge number of industrial assets, along with the safety of the personnel operating them and in some cases living close to them.
Highly attenuative materials pose an increased challenge when UT on them is attempted.
Moreover, early stage defect identification relies on high frequency HFUT to achieve high resolution imaging and again suffers from the fast attenuation of HFUT.
In addition to that, high temperature inspection suffers from poor transducer response that in turn is an attenuation issue.
A technique that could improve the depth penetration of acoustic waves alongside increases in the Signal-to-Noise-Ratio (SNR) can significantly expand the types of assets that can be inspected along with the achieved resolution.
This can lead to better inspections and increased safety.

PhD Research Topic Outcomes and Impact
This research is expected to be the first step in paving the way to increase adoption of coded excitation ultrasonic techniques in the industry.
It will seek to prove that the acoustic wave generation and interaction with defects does not alter the UT technique if longer pulse trains are utilised and the interaction signal is artificially synthesized through signal processing.
At least 2 peer reviewed papers (targeting IEEE journals) are expected, containing a mix of simulation and experimental results.
Coded excitation is expected to be one of the next radical capability enhancements to be included in the next generation(s) of ultrasonic testing equipment.
This research work will address the hardware requirements for it since a variety of electronics will be used and compared.
Also we expect that the papers and thesis to become references when the standards describing the ultrasonic equipment requirements will be updated.
Ultrasonic inspection of thick composite sections, graphite rods (nuclear), stage I creep alongside elevated temperature and ATEX Zone 0 monitoring are few examples of applications that we expect to be enabled by this type of pulsing and signal processing.
