Dynamic fatigue experiments were performed on Z5U multilayer capacitors in an attempt to correlate microflaw fracture behavior due to intrinsic processing defects within the material with predictions of fracture behavior based on macrocrack fracture mechanics determinations. A direct correlation between microflaw fracture behavior and predictions based upon macrocrack fracture mechanics techniques was not observable due to the wide size range of processing defects. A systematic post-mortem examination of fracture surfaces was used to identify fracture origins and sort individual test specimens into groups with equivalent flaw sizes. The correlation between microflaw and macrocrack fracture behavior became more “sorting” the dynamic fatigue data into groups withm oereq uoibvvailoeunst aflfatwer sizes.
