Abstract
FIELD: study of materials and their capability to resist to cracks growth depending on their fraction pattern parameters in the form of slant caused by plastic deformation, method is used for estimation of loading of structure members. SUBSTANCE: method provides, that samples are cyclically loaded under different asymmetry of cycles. Values of crack length and slants height caused by plastic deformation are determined and according to their correspondence judgement about equivalent damaging action of loadings is made and dependance between equivalent factor of tension intensity and slant height caused by plastic deformation is determined. On structural member surface, which developed fatigue crack, measurements of space between trace of crack and distant from it boundary of plastic deformation zone are made and simultaneously crack length is measured. About parameters of fatigue crack growth they charge according to single ratio between measured space and equivalent factor of tension intensity using for the purpose measurements of crack length. EFFECT: method allows to estimate structure members loading. 1 cl, 4 dwg
