Stress Tensor of a Finite Dislocation

概要

論文の詳細を見る
Expressions for the stress field of a dislocation segment are given in a general dyadic form, without reference to a particular coordinate system. They are derived from the formulae of peach and Koehler, and limited to the case of a linear, isotropic, infinite continuum. The stress tensor due to a finite length of dislocation is expressed in the form cσ^∞+σ', which in the extreme case reduces to σ^∞, the well-known result of an infinitely long dislocation. The stress field of an arbitrary dislocation network can be deduced by the simple addition of the stress field of each component segment, as a direct application of the present study.
