This paper deals with the relations between the continuous distribution of circular twist disclination loops and the penny-shaped crack of type III. Based on the stress and displacement field of a circular twist disclination loop in an infinitely extended medium and those of a penny-shaped crack of type III given by the potential theory, the distribution function of disclination can be obtained by solving the Abel-type integral equation generated by the equivalency of the shear stress field over the crack surface. Furthermore, the distribution function thus derived can also be confirmed by the equivalency of the displacement field over the crack surface. Consequently, it can be concluded that a penny-shaped crack of type III can be represented by a continuous distribution of a circular twist disclination loops.
