Frictional Force Acting on a Dislocation : Fluttering Mechanism
スポンサーリンク
概要
- 論文の詳細を見る
The frictional force acting on the dislocation is calculated for the fluttering mechanism based on the continuum approximation. It is shown that the equations of motion lead to the inelastic scattering of thermal phonons, resulting in transfer of their momentum to the dislocation. The frictional force by this mechanism has the T^3-dependence at low temperatures. If we use the Debye cut-off, the magnitude is about 1.6×10^<-4> dyne・sec/cm^2 for Cu at room temperature.
