摘要
本文发展了立方准晶的位错弹性理论 ,通过立方准晶的反平面弹性问题的控制方程 ,得到了其含有螺型位错时的位移场与应力场的解析表达式。为研究此固体材料的塑性变形提供了重要信息。
The elasticity theory of dislocation of cubic quasi crystal is developed, and analytical expressions of displacement and stress fields for screw dislocation in cubic quasi crystal are obtained by using governing equations of anti plane elasticity problem of the quasi crystal.These provide important information for studying the plastic deformation of the new solid material.
