Effect of environment and electric field on delayed fracture of piezoelectric ceramics

Static 4-point bending tests have been carried out with poled PZT under various environmental conditions. The average value of applied stress at which fracture occurred within 48 hours was defined as the delayed fracture strength σdf, and the effects of the environment and the electric field on the...
