摘要: Abstract The fracture behavior of four non-symmetric radial cracks originating from a circular hole in piezoelectric materials subjected to remotely uniform in-plane electric loading and anti-plane mechanical is studied this paper. problem transformed using the complex variable method technique conformal mapping into Cauchy integral equations. To solve equations, analytical solutions stress displacement intensity factors, energy release rate strain are obtained under electrically impermeable permeable assumptions, respectively. Several known results special cases present new models used for simulating more practical defects derived as well, such three hole, semi-circular with an edge crack semi-infinite plane crack. Numerical examples provided graphically show effects geometrical parameters on rate.
