Uchimoto-Lesmana Lab
Machine-translated · View original
A lab that measures material damage without destroying the material, supporting the safety of equipment.
AboutAbout the lab
Finding damage without breaking anything.
The Uchimoto Lab studies nondestructive evaluation technologies that support the safety and reliability of industrial and energy systems.
Using electromagnetic and acoustic (ultrasonic) methods, the lab detects degradation, defects, and damage in metals and composite materials, and quantifies their extent.
It combines high-accuracy modeling with inverse analysis.
By combining multiple sensors and collaborating with researchers in materials science and data science, the lab aims to develop inspection and monitoring methods that can be used in the field.
Key terms
- nondestructive evaluation
- An inspection approach that examines internal flaws and degradation in a component without breaking or cutting it
- eddy current testing
- A method that induces swirling electric currents in metal and detects flaws near the surface from disturbances in those currents
- acoustic emission
- A method that picks up the very faint sounds a material emits when it cracks, in order to trace how it fails

ResearchResearch themes
In next-generation transportation systems and energy plants, it is important to rationally manage the degradation and damage of structural materials caused by flow. The lab develops electromagnetic nondestructive evaluation, acoustic emission, and sensors usable in high-temperature environments, aiming to apply them to online monitoring.

The lab works on electromagnetic sensing and nondestructive evaluation methods, including eddy current testing, the incremental permeability method, and electromagnetic acoustic transducers (EMAT).
*Illustrative imageTracing how materials fail with sound and ultrasound
The lab works on nondestructive evaluation using sound and ultrasound, including acoustic emission (AE) monitoring, ultrasonic testing, and methods based on nonlinear ultrasonics.
*Illustrative imageMaterial damage under hydrogen and high temperature
The lab works on evaluating hydrogen embrittlement, high-pressure hydrogen equipment, material degradation caused by corrosion and similar factors, and materials evaluation for equipment used at high temperatures.
*Illustrative imageInspecting additively manufactured parts
The lab works on nondestructive evaluation and defect detection for components made by additive manufacturing (metal 3D printing). It also studies digital twins for structural integrity and the application of machine learning to inspection.
