Using a networked specimen, the distribution of strains both during and after rolling were investigated. The networked lines were carefully scratched at 1.0 mm distance on a vertical section of a square Cu bar. In this paper,the effects of rolling reduction by the pass and the number of repeated passes through the rolls to certain reduction in relation to the magnitude of the axial, vertical and additional shearing strains were described. The results obtained were as follows: (a) Strains in half-rolling (1) In the lower reduction (1.5 & 4.1%), deformation in the central portion of the bar begins earlier than in the outside layer. In contrast to this, in higher reduction (8.2 & 28.5%), the outside layer deforms earlier than the central past. The deformation of the outside layer wes retarded in completion the central portion, regardless of the magnitude of the rolling reduction by the pass. (2) The shape of the transverse lines was not always straight and perpendicular to the rolling direction in the deformation area. (b) Strains after rolling (1) The magnitude of rolling reduction and the number of repeated passes through the rolls do not appreciably affect the uniform distribution of the axial and the vertical strains in the vertical section except in an extremely thin layer of the surface. (2) The additional shearing strain was always the greatest in the outside layer and zero in the central portion of the bar.
