摘要
Both dynamic and static three-point bending fracture testings of 32 piezoelectric ceramic samples were performed in four different poling directions. A modified split Hopkinson pressure bar method with a polyvinylidene fluoride (PVDF)-based gauge was utilized for the dynamic experiments. The loading rate greatly influenced the fracture toughness in two ways: the dynamic fracture toughness values were much higher than those of the static fracture toughness, and unlike the static fracture toughness, the influence of poling direction on the dynamic fracture toughness was not obvious.
