Crack Identification Log For Free

Which methods are available for the detection of cracks in cast components? Visual Inspection (VT) Dye penetrant testing (PT) Eddy current testing (ET) Thermographic tests (TT) Magnetic particle testing (MT) Ultrasonic testing (UT)

When a crack occurs, the optical fiber is disconnected, and the light leaks from the disconnected part. This light leakage enable you to know the occurrence and position of the crack as a light emission from the sensor.

Several other crack detection methods are in common use, including magnetic particle inspection, dye penetrant inspection and ultrasound. For magnetic particle inspection and dye penetrant inspection many chemical preparations are used. These include solvents, dyes and 'developers'.

Crack identification in structures by detecting changes in their dynamic behavior has been studied in the past, and various methods have been developed, enabling the calculation of crack location and depth along a beam. ( 1) ~ (4) Most of these methods utilize the frequency changes caused by the crack.

Crack analysis is indispensable to clarify the various mechanisms by which cracks occur and evaluate the damaging effects that these cracks inflict on concrete structures.

A crack in any material is a point of weakness and any stresses put on the material could lead to the crack widening and leading to shearing and splitting. Cracks can occur during manufacture, as a result of poor welding or due to stresses placed on equipment during work.

Crack detection is the process of detecting cracking, usually through non-destructive testing (NDT). Early detection enables preventative action to mitigate potential failure and ensure operations efficiency.
