| 内容記述 | The effects of strain rate history on the compressive stress-strain curves of mild steel and pure copper were examined. The dynamic compressive tests at the strain rate of about 200~500 1/s and the static ones at 3.8×10⁻4 1/s were done by a dynamic testing device of Hopkinson bar type and an universal testing machine of constant velocity type respectively. Consequently the following were obtained. For mild steel, the stress in dynamic reloading after static prestraining is higher than that in initial dynamic loading without prestraining. And the stress in static reloading after dynamic prestraining is lower than that in initial static loading. In other words, dynamic loading causes less strain hardning than static loading. For pure copper, reversely, dynamic loading causes more strain hardning than static loading. And also proportional expressions are formed between the static prestrain and the dynamic prestrain for the both materials. As a result, it was found that the stress-strain curves including strain rate history can be formularized by using a parameter whose increment is proportional to strain increment. |
