Abstract
Cyclic plastic-straining tests have been conducted in push-pull on cylindrical specimens and in uniform bending on rectangular-section bars of mild steel (B.S. 1501–161 Grade 28A) and of stainless steel (En 58J). The mild-steel specimens were tested at room temperature and 350°C, the stainless-steel specimens at room temperature and 650°C. It is found that there is good correspondence between cyclic stress-strain relations (the cyclic semi-range of strain and the corresponding cyclic semi-range of stress) derived from bending tests, when an expression analogous to that developed by Nadai for monotonic straining is used, and those obtained more directly from push-pull tests.Keywords
