Description

осуществл ют нагружающим устройством пуансоном 4. В образце 3 возникает напр женное состо ние, близкое к двухосному ; раст жению. Раскрытие трещины 9 регистрируют приемником 7 из-за увеличивающего. с  светового потока через трещину от источника света 6.carried out by a loading device punch 4. In sample 3, a stress state that is close to biaxial arises; stretching. The crack opening 9 is recorded by the receiver 7 due to the magnifying one. from the light flux through the crack from the light source 6.

Отсутствие при нагружении свободных относительных перемещений межцу образцом , источником света и приемником света обеспечивает высокую точность измерени .The absence of free relative displacements between the sample, the light source and the light receiver during loading ensures high accuracy of measurement.
