Yield Point Phenomena and their Theoretical Background

  • E. O. Hall


When certain materials such as mild steel are deformed in tension, it is found that the stress-strain curve is not smooth, but shows marked irregularities, with negative slopes occurring at or near the initial yield on the curve. The actual shape of the stress-strain curve is dependent, to some extent, on the type and characteristics of the tensile testing machine used; nevertheless one may include all cases where δσ/δ∈ is negative as examples of yield point effects deserving attention.
