位错应力场的连续介质模型

从弹性力学的基本公式出发，把固体材料当作准连续介质，研究了影响材料强度的主要缺陷位错引起的应力场的数学表达形式，根据力场间的相互作用原理，讨论了直线位错间的相互作用力和相互作用能的计算方法，教学计算结果表明，位错应力场与电磁场可以具有类似的表达形式，也具有一些类似的性质。

Continuous Medium Model the Dislocation Stress Field

Based on the fundamental equations of elasticity mechanics, the mathematical formcaused by the dislocation stress field which affects the strength of materials is studied with solidmaterials as semi - continuous media. According to the principle of force field interaction, thecalculating method of the interaction force and interaction energy between the line dislocation stressfield is discussed.The result shows that the dislocation stress field and the electromagnetic field havesimilar form and characteristics.
