| 摘 要： | 通过复变函数论的方法,对I型运动裂纹面受双重载荷、瞬时冲击载荷作用下的位错分布函数问题分别进行研究．采用自相似函数的方法可以获得运动裂纹的应力、位移、应力强度因子及位错分布函数的解析解,应用该法可以迅速地将所论问题转化为Riemann-Hilbert问题,并可以相当简单地得到问题的闭合解．

| Abstract: | By application of the method of the theory of complex functions,the problem on dislocation distri- bution function of the edges of the mode I moving crack subjected to superimpose and impact loads is studied respectively.Analytical solutions on stresses,displacements,dynamic stress intensity factors and dislocation distribution function of moving crack are attained by the ways of self-similar functions.The problems can be transformed into Riemann-Hilbert problems and their closed solutions are obtained rather simple by this method. |
