WebThe equation for change in length is traditionally rearranged and written in the following form: F A = Y Δ L L 0. 5.34. The ratio of force to area, F A, is defined as stress (measured in N/m 2 ), and the ratio of the change in length to length, Δ L L 0, is defined as strain (a unitless quantity). WebA stress-strain curve typical of structural steel 1. Ultimate Strength 2. Yield Strength 3. Rupture 4. Strain hardening region 5. Necking region. Steel generally exhibits a very linear stress-strain relationship up to a well defined yield point (figure 1). The linear portion of the curve is the elastic region and the
