Dynamic Tensile Strength of a Ferroelectric Ceramic

The dynamic tensile strength of a piezoelectric lead titanate zirconate ceramic used for power transducers was tested by driving small bars of ceramic electrically at their longitudinal resonance until they fractured. The measured dynamic tensile strength of small specimens of ceramic of good quality was found to be about 13 000 psi. This value was very drastically reduced for ceramic which was not of optimum quality.
