Diagnosting of the Predestruction Condition of Metal Constructions Elements
Stability of the stress-strain state of structural steel, aluminum and copper alloys samples subjected to long-term (more than 5 years) static loads of various levels by X-ray diffractometry was established. The results of determining the state of pre-destruction from the change in the characteristics of the diffraction profile are described and discussed. It has been shown experimentally that the load-carrying capacity of metal constructions under static operating loads developing elastic stresses in the area of their concentration, within the limits up to σ = 0,4... 0,5σ0.2, does not decrease.
