| 摘 要： | 本文用量纲分析的方法,首次得到了非线性介质(通常是指Hencky弹塑性或非线性弹性介质)中运动裂纹的动能公式,而著名的Mott公式只是本文结果的特例,即当介质由非线性变成线性时,本文的动能公式与Mott公式完全一致。 |

| Abstract: | Applying the dimension analysis method, the Kinetic energy formula for a moving crack in elasto-plastic medium is deirved.it will be reduce to the well-known Mott's formula when the medium is restricted to a linear elastic one.In this sense it is seen that the Mott's formula is only a special case of the result obtained by this study. |
| Keywords: | power law hardening Asympfotical fields of displacemont in craek tip Dimensim analysis formula of kinetic energy of a moving crack |
