Laws of mesostrain distribution in aluminum strip rolling

Abstract

Experimental results have determined the mesostrain characteristics of aluminum in a plane stress-strain state. Tensor components of plastic deformations are defined for grains in a plane of a rolled aluminum sheet. The intensity of principal mesostrains is calculated. The correlation between deformations of individual parts is estimated by the Z-normalized autocorrelation functions. Strain distribution laws are formulated. Parameters of stress-strained grains are indicated. © 2016 Author(s).
