| Abstract: | By means of the theory of complex functions, fracture dynamics problems of mode I semi- infinite crack for anisotropic orthotropic
body were researched. Analytical solutions of stress, displacement, and dynamic stress intensity factor under the action of
moving increasing loads Px

3, Pt
4/x
3, respectively, are very easily obtained utilizing the approaches of self-similar functions. In the light of relevant material’s
coefficients, the alterable rule of dynamic stress intensity factor was depicted very well. The correlative closed solutions
are attained based on the Riemann–Hilbert problems. After those analytical solutions were applied by the superposition principle,
the solutions of discretional complex problems could be attained. |
