An anti-plane shear problem of a piezoelectric material containing a center crack is analyzed. A general solution for the stress intensity factor is obtained. The boundary collocation method is used to calculate the relationship between the stress intensity factor and section geometry. It is shown that the method of half analytical and half numeral is accurate, simple and widely applicable.
