Abstract: The aim of this paper is to investigate the influence of residual stresses, due to cold-drawing, on the shape of the tensile stress-strain curve and particularly its influence on the ratio (sigma) 0.
2/(sigma) max through a numerical and experimental work.
It was found that residual stresses favours the onset of yielding and the ratio (sigma) 0.
2/(sigma) max decreases with increasing values of residual stresses.
Because of the deleterious effect of residual stresses on fatigue and stress corrosion and because such stresses affect the ratio (sigma) 0.
2/(sigma) max, it is reasonable to put a lower limit to (sigma) 0.
2/(sigma) max in the standards.
The ratio (sigma)0.
2/(sigma) max can be increased by relieving residual stresses, a common procedure after drawing.
This fact is also ascertained.
