Abstract

Elasto-plastic crack solutions for some one- and two-dimensional quasicrystals have been found based on the generalized Dugdale–Barenblatt model. The size of the plastic zone and crack tip opening displacement are determined, from which a plastic fracture criterion for the materials is suggested.
