摘要：
The finite element formulation for analyzing static damage near a conducting crackin a thin piezoelectric plate is established from the virtual work principle of piezoelectricity.Thedamage fields under various mechanical and electrical loads are calculated carefully by using aneffective iterative procedure.The numerical results show that all the damage fields around a cracktip are fan-shaped and the electric field applied has great influence on the mechanical damage,which is related to the piezoelectric properties.
