Abstract

This paper presents the results of an analytical and experimental investigation in fatigue crack growth behavior of piezoelectric ceramics under electromechanical loading. Static fatigue tests are performed in three-point bending with the single-edge precracked-beam piezoelectric specimens under electric fields. Time-to-failure under different mechanical loads and electric fields are measured, and the effect of applied electric fields on the energy release rate vs lifetime curves are discussed, with combination with the finite element method. Cyclic crack growth tests are also conducted on the same piezoelectric specimens under electric fields, and the fatigue crack growth rate vs maximum energy release rate curves are examined.
