Fracture criterion for a conducting crack in poled PZT-PIC 151 investigated by stable crack growth

The fracture behavior of conducting cracks in PZT (PIC 151) was investigated under combined mechanical and electrical loads in four-point bending. Controlled crack growth in a single-edge V-notch beam (SEVNB) specimen was achieved in a very stiff displacement controlled device. During the experiment...
