Investigation of the Hysteresis Phenomenon for a Metal Wire Stretched Statically |
| |
| Abstract: | Hysteresis Phenomenon can be observed obviously in the experiment of Determination Young’s Mod-ulus for a Metal Wire. This thesis shows the hysteresis phenomenon on a metal wire which is stretched statically by means of measuring data and elastic characteristic curves. Quantity of the hysteresis is calculated roughly. |

| Keywords: | elastic hysteresis static stretch Young’ s modulus |
