摘要

摘要通过在Burgers向量中加入线力，对边缘位错弹性场的经典描述进行了修正。此外，位移的划分是强加的，与界面缺陷的拓扑理论一致，符合非线性或原子计算中固有的对称性要求。许多经典理论没有改变。但是，位移场和图像效果不同。关键词:脱位;脱节;断连安德森，D.M.巴奈特和R.C.庞德。审稿人的评论是有价值的。披露声明作者未报告潜在的利益冲突。

Modification of the elastic field of an edge dislocation

ABSTRACTThe classical description of the elastic field of an edge dislocation is modified by the addition of a line force to the Burgers vector. Also, partitioning of displacements is imposed, consistent with the topological theory of defects at interfaces, agreeing with symmetry requirements as are inherent in nonlinear or atomistic calculations. Much of the classical theory is unchanged. However, displacement fields and image effects differ.KEYWORDS: Dislocationdisclinationdisconnection AcknowledgementsHelpful comments were provided by P.M. Anderson, D.M. Barnett, and R.C. Pond. Comments by a reviewer were valuable.Disclosure statementNo potential conflict of interest was reported by the author(s).
