Analytic solutions to problem of elliptic hole with two straight cracks in one-dimensional hexagonal quasicrystals

摘要

By means of the complex variable function method and the technique of conformai mapping,the anti-plane shear problem of an elliptic hole with two straight cracks in one-dimensional hexagonal quasicrystals is investigated.The solution of the stress intensity factor(SIF)for modeⅢproblemhas been found.Under the condition of limitation,both the known results and the SIF solution at the crack tip of a circular hole with two straight cracks and cross crack in one-dimensional hexagonal quasicrystals can be obtained.
