Yuki Lab
Machine-translated · View original
A lab that studies how things break by listening to the sounds they make, and develops educational support systems for design and drafting.
AboutAbout the lab
Listening to the cries of things, and building tools that help people understand.
The Yuki Lab studies acoustic emission (AE) and educational support systems for design and drafting.
AE is a phenomenon in which elastic waves are generated when a sudden change occurs in a solid, such as when a crack forms. The snap you hear when breaking disposable chopsticks is also a kind of AE.
The AE method measures AE to examine its magnitude and frequency of occurrence, or analyzes its waveforms, in order to learn how things break and where damage is located.
In its other main area of research, the lab develops computer-based active exercise systems that help students build the ability to visualize the motion of mechanisms and to read and produce drawings.
Key terms
- Acoustic emission
- A phenomenon in which elastic waves are generated when a sudden change occurs in a solid, such as when a crack forms. The sound of breaking chopsticks and earthquakes are also kinds of acoustic emission.
- AE method
- A technique that examines the magnitude and frequency of AE, or analyzes its waveforms, to learn how things break and where damage occurs.

The Yuki Lab studies acoustic emission, which investigates how things break by using the elastic waves released when a solid fractures. The lab also studies educational support systems for design and drafting, which support the ability to understand mechanisms and drawings that mechanical engineers need.
