| 摘 要： | 针对含有裂纹的导电平板提出一种计算电流密度分布的新方法。该方法通过构造含有圆孔簿板的势函数并将其转换为复位函数，成功地求解含有裂纹导电薄板的电流密度分布，进而揭示裂纹尖端的电热效应集中现象，为电热裂纹止裂提供理论依据和计算方法。

| Abstract: | In the light of thin conductive plate with a crack,a new method is introduced to calculate the distribution of electric current density.This method,which through the construction of potential function for thin plat with a circular hole and then changes them into complex potential function,can successfully finds the solution of the distribution of electric current density in conductive thin plate.Then the phenomena of electrothermic effect's concentration around the crack tip are revealed.All these provide theoretical foundation and calculate method for electro-heat crack arrest. |
