A decagonal quasicrystal with a Griffith crack
A decagonal quasicrystal with a Grina th crack,-0001,():
The crack theory in conventional linear elasticity fracture mechanics is extended to quasicrystal linear elasticity fracture mechanics. A decagonal quasicrystal containinga Gri th crack penetrating through the solid along the period direction is considered. By means of a general solution, the analytical expressions for the entire stress field are obtained. The asymptotic behaviour of the stress around the crack tip indicates that the stress near the crack tip exhibits the square root singularity. The singularity in the phason stress field arises from that the phononandphason fields couplewitheach other. The crackstrain energy and energy release rate are also given.
