Abstract
'This paper treats the crack-microcrack interactions in an anisotropic piezoelectric solid. Based on the Green's function approach and the principle of superposition, a system of singular integral equations for the unknown temperature discontinuity and elastic displacement-electric potential(EDEP) defined on each crack trace is developed and solved numerically. In the analysis, the residual heat flux, stress and electric displacement (SED) on microcrack location to be released are evaluated directly from the near-tip fields of main crack. Numerical results for SED intensity factors in a three-crack system are presented to illustrate the application of the proposed formulation.
