Abstract:The displacement discontinuity and potential discontinuity fundamental solutions (DDFS), which are of great importance in the analyses of crack problems with Boundary Integral Equation Method (BIEM), are obtained for the case that the material characteristic equation of piezoelectric medium has identical roots. This is the complementary part of the pevious studies .
Keywords:piezoelectric media  fundamental solution  fracture mechanics
