Mh. Zhao et al., ISOLATED CRACK IN 3-DIMENSIONAL PIEZOELECTRIC SOLID .1. SOLUTION BY HANKEL TRANSFORM, Theoretical and applied fracture mechanics, 26(2), 1997, pp. 129-139
The fundamental solutions are obtained for a unit concentrated electri
c potential discontinuity and unit concentrated displacement discontin
uity in a three-dimensional piezoelectric medium. Displacements and st
resses are derived by application of the boundary integral equation me
thod. These expressions are used to obtain the stress intensity factor
s for a circular crack in Part II of the study.
