The present work is concerned with a penny-shaped Dugdale crack embedded in
an infinite space of one-dimensional (1D) hexagonal quasicrystals and subjected to two identical
axisymmetric temperature loadings on the upper and lower crack surfaces. Applying Dugdale
hypothesis to thermo-elastic results, the extent of the plastic zone at the crack tip is determined.
The normal stress outside the plastic zone and crack surface displacement are derived in terms of
special functions. For a uniform loading case, the corresponding results are presented by simpli-
fying the preceding results. Numerical calculations are carried out to show the influence of some
parameters.
