- Abstract
The paper presents results of correlation analysis of longitudinal strain values at different times during uniaxial tensile loading of flat specimens of technically pure A7-grade aluminum. The factor analysis allows distinguishing several factors responsible for the coordinated change of surface deformations at different deformation stages. Three characteristic zones are identified for the correlation matrix and diagrams of factor loads, which are correlated with the stages on the deformation curve. The factors are described in accordance with the stages of the deformation process, and their interpretation is proposed through the initial variables: the distribution of deformation values over the sample surface and time.
