This paper verifies two laws for plastic flows of face-centered cubic crystals that deform at constant strain rates and fixed ambient temperatures. The first law relates steady-state flow stress to ambient temperature and strain rate. The second law requires an increase of configurational entropy towards a maximum reached in the steady state. The large scale least squares analysis is provided which allows the physics-based parameters of thermodynamic dislocation theory to be identified in accordance with these laws.

塑性流动的两个普遍定律和一致的热力学位错理论

本文验证了在恒定应变率和固定环境温度下变形的面心立方晶体塑性流动的两个定律。第一定律将稳态流动应力与环境温度和应变率联系起来。第二定律要求配置熵增加到稳态时达到的最大值。提供了大规模最小二乘分析，它允许根据这些定律确定热力学位错理论的基于物理的参数。
