The study investigates how strain rate and temperature affect the yield stresses of mild steel. Tensile tests were conducted at room temperature and 200 °C, 400 °C, 600 °C over strain rates from 10⁻⁸ to 10³ s⁻¹, and the resulting data were plotted to analyze strain‑rate effects on yield and ultimate stresses. The experiments identified the conditions that produce discontinuous yielding and compared them with observed test behavior.
Abstract This paper describes the influence of rate of strain and temperature on the yield stresses of mild steel. Tensile tests are reported for room temperature, 200, 400, and 600 C, at rates of strain which vary from 10−8 to 103 per sec. The results of these tensile tests are plotted to show more clearly the effects of strain-aging on the yield stresses and ultimate stress. The comparison of the yield stress at various strain rates permits an analysis of the influence of strain. The conditions necessary for discontinuous yielding are described and compared with test experiences.
