讨论了有限弹性静力学中位错问题表述中出现的跳跃条件，并给出了螺旋位错问题的反平面剪切型全场解。该解对于最一般的均匀各向同性不可压缩非线性弹性固体是有效的。该解决方案定义了非线性水平，并与材料科学中的“位错核心”估计进行比较。
The jump conditions arising in the formulation of dislocation problems in finite elastostatics are discussed and a full field solution of the anti-plane shear type is given for the screw dislocation problem. The solution is valid for the most general homogeneous isotropic incompressible nonlinear elastic solid. The level of nonlinearity is defined for this solution and compared to "dislocation core" estimates in materials science.
