Critical Data for Reproducing Results in Paper "Critical Operating Stress of Persistent Slip Bands in Cu". Abstract of the paper: This work elucidates the dependence of operating stress of persistent slip bands (PSB) on the channel width and wall dislocation density. Using Cu as a model system and molecular dynamics as the main investigative tool, a new length scale effect, namely the wall dislocation spacing, is provided to enhance theoretical understanding of PSBs. It is discovered that the operation of PSB is a thermally activated event in which operating stress is inversely related to the wall dislocation spacing, strain rate and temperature. Leveraging the existing framework of confined layer slip in nanoscale metallic multilayers and classical nucleation theory, a mathematical model describing the rate- and temperature- dependent PSB operating stress is proposed.用于复现论文《铜中持久滑移带的临界启动应力》结果的关键数据集。 论文摘要：本研究阐明了持久滑移带（Persistent Slip Bands, PSB）的启动应力与通道宽度以及壁位错密度的依赖关系。本研究以铜作为模型体系，以分子动力学为主要研究手段，提出了一项新的长度尺度效应——壁位错间距，以深化对持久滑移带的理论认知。研究发现，持久滑移带的启动属于热激活过程，其启动应力与壁位错间距、应变速率以及温度呈反比关系。本研究借助纳米金属多层膜受限层滑移的现有理论框架与经典形核理论，提出了一个描述应变速率与温度依赖型持久滑移带启动应力的数学模型。
