| Abstract: | The axisymmetric elasticity problem of cubic quasicrystal is reduced to a single higher_order partial differential equation by introducing a displacement function. Based on the work, the analytic solutions of elastic field of cubic quasicrystal with a penny_shaped crack under the shear loading are found, and the stress intensity factor and strain energy release rate are determined. |
