Summary / Conclusions<br />

In the present study the 3-point bending ceramic test was<br />

carried out to clarify the relation between strength and flaw<br />

size at a fracture origin.<br />

The 3D bending model <strong>of</strong> ceramic has been created to study<br />

and to correlate the stress concentration and material<br />

displacement <strong>of</strong> fracture materials.<br />

The SEM images <strong>of</strong> broken ceramic specimens were used to<br />

understand material structure, to determine size <strong>of</strong> flaws and<br />

stress intensity factors.<br />
