The Dynamic Peieris-Nabarro Dislocation

本文研究了加速运动位错的能量学，这对理解位错的运动是很重要的 的微观机制 变形 在高应变率下的韧性材料。 佩尔斯-纳巴罗 该模型已成功用于 静态变形，并正在扩展到动态瞬态运动。近动位错的产生和运动问题 休克 阵线和运动 的 双胞胎 都得到了解决。

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.
