Background
Stress corrosion refers to the destruction of a metal in a corrosive medium under force. This corrosion is generally through the grain, so-called transgranular corrosion. Stress corrosion is a material failure process resulting from the combined effects of strain and corrosion caused by residual or applied stress. Stress corrosion induced cracking of a material is known as stress corrosion cracking.
The weight of material itself also can produce stress, and some objects receive the action of gravity and can produce obvious deformation to produce stress, for example: steel bars, cables and the like are objects whose length is much greater than their width and thickness. The deformation of the object is closely related to the placing angle of the object.
When the stress corrosion research is carried out on the objects, the test sample piece needs to be soaked in a test solution and then taken out and dried for detection; then, changing the placing angle of the next group of measured objects requires manually readjusting the positions of the fixing pieces for fixing the objects, so that the placing angle of the measured objects is adjusted. This adjustment is slow, resulting in inefficient testing.
