tin cry

Japanese: tin cry（英語表記）tincry

...It is used as a non-destructive testing method for solid materials and structures such as metals, ceramics, and rocks, and as a means of studying their plastic deformation and destruction phenomena. A well-known example of an audible sound is the tin cry that occurs when metal tin is bent, but generally it is ultrasonic, and is detected electrically by attaching an AE transducer to the solid sample. Generally, before an object breaks, very fine cracks occur inside it, which grow and lead to destruction. ...

…金属，セラミックス，岩石など固体材料および構造物の非破壊検査法，これらの塑性変形や破壊現象の研究手段として利用される。可聴音の例としては金属スズを曲げたときに発生するスズ鳴りtin cryが有名であるが，一般には超音波であって，固体試料にAE変換子を付けて電気的に検出する。一般に物体が壊れる前にその内部では非常に微細な割れが発生し，それが成長して破壊にいたる。…
