论文摘要
本文研究了平面限制了具有一个活跃滑动系统的单晶的剪切问题，并在LE（2018）提出的小应变热力学脱位理论中均载有两个方向的负载。边界价值问题的数值解决方案显示了各向同性和运动学工作硬化，应力 - 应变曲线对温度和应变速率的敏感性，鲍申格（Bauschinger）效应以及尺寸效应。
This paper studies the plane constrained shear problem for single crystals having one active slip system and subjected to loading in both directions within the small strain thermodynamic dislocation theory proposed by Le (2018). The numerical solution of the boundary value problem shows the combined isotropic and kinematic work hardening, the sensitivity of the stress-strain curves to temperature and strain rate, the Bauschinger effect, and the size effect.
