Residual Stress in Cold Drawn Aluminum Bar

Abstract

Residual stresses in aluminum bar specimens cold drawn to cross-sectional reductions from 23 to 81% were measured. The preferred orientation of each part in the cross-section on these specimens was measured.
It was shown that the preferred orientation in each part changed by drawing was closely correlated with the residual stress.
The effect of the fiber texture on the generation of residual stresses was investigated. A rather high residual shearing stress which was concerned with the normal directional residual stress was produced between the surface and the inner neighboring part under the surface by drawing.
