Denis Goto
RESEARCH PROFILE
Time-of-Flight Diffraction (TOFD) is an ultrasonic non-destructive evaluation technique used to measure the size of defects. Denis' research is focused on improving the measurement accuracy of TOFD for the inspection scenario found in welds in steel bridges. His research profile involves aspects such as:
- Simulation of ultrasonic wavefield (Finite Difference and Ray tracing techniques)
- Error propagation and modelling the inspection procedure (Monte Carlo technique)
- Ultrasonic imaging (Synthetic Aperture Focusing technique - SAFT)
- Signal deconvolution
Accurate sizing of defects becomes relevant as engineers strive for better estimation of the remaining service life of existing civil infrastructure. Fatigue life estimation is the main topic of the research project in which he is involved and it also appears in several other projects of the Aluminum and Steel Group.
ACADEMIC BACKGROUND
Denis' academic background is on mechanical/aerospace engineering. He developed expertise in the field of Non-Destructive Evaluation from two work experiences:
- Laboratory of metrology at Federal University of Santa Catarina (Brazil)
- Opto-NDT group in the Aerospace faculty of TU Delft (Netherlands)
In these two groups, he was involved with developing an equipment using shearography, an optical interferometric technique.
His academic background in complemented by 8 years of experience in the industry as mechanical engineer and 2 years as project manager.
