True Stress Calculation for Tension Tests Prior to Necking

CODEN: JTEVAB

Abstract

In determining true stresses prior to necking, the relationship usually employed is σ=S(1+e). The derivation of this expression involves approximating the gage section volume as being constant. However, this approximation is not necessary. A more exact but implicit relationship for σ is developed and compared with the traditional expression.
