摘要
本文由位错连续统规范场理论讨论了位错分布与应变张量场之间的关系.得出一个给定的位错分布可以存在多个弹性应变张量场及塑性应变张量场.这些应变张量场之间的关系由畸变张量的等位错分布变换确定.而总应变张量场与这个变换无关.
In this paper,the relationship between the distribution of dislocationsand strain tensor field is discussed from the viewpoint of the gauge theoryof dislocation continuum.It is obtained that a fixed distribution ofdislocations corresponds to many elastic strain tensor field and plasticstrain tensor fields,The relationship in those strain tensor fields isdetermined by the so-called iso-dislocation-distribution transformation ofdistortion tensor.But the total strain tensor is irrelevant to thistransformation.
