It can be translated into a Riemann-Hilbert problem by means of self-similar functions, and the universal representations of analytical solution were obtained when there is $Pt / x$ or $Px^3 / t^2$ load at the origin of the crack coordinates.

采用自相似函数的方法可以轻易地将所论问题转化为Riemann-Hilbert问题，并求得了裂纹坐标原点分别受到变载荷$Pt/ x$，$Px^3 /t^2$作用下的解析解的一般表达式。

The results show that using the theory of complex functions, the problems discussed can be easily translated into Riemann-Hilbert problems. Analytical solutions of the displacements, stresses and dynamic stress intensity factors under the action of increasing loads Px/t and Pt^3/x^2 situated at the origin of the coordinates of propagation crack, are gained by self-similar approaches.
