The Dynamic Peieris-Nabarro Dislocation

研究了位错随加速度运动的能量学，这对于理解塑性材料在高应变率下动态变形的微观机制具有重要意义。Peierls-Nabarro模型已成功地用于静态变形，并正在扩展到动态瞬变运动。讨论了运动激波阵面附近位错的产生和运动以及孪晶的运动问题。

The energetics of dislocations moving with acceleration are studied which are important for the understanding of micromechanisms underlying the dynamic deformation of ductile materials under high strain rates. The Peierls- Nabarro model has earlier been succesful for static deformations and is being extended to dynamic transient motion. Issues of generation and motion of dislocations near moving shock fronts and the motion of twins are addressed.
