Mechanical behavior of ceramics. Following a single procedure we studied the strength the deformability and the crack resistance of a number of ceramics based on zirconium dioxide containing stabilizing additives magnesium oxide or yttrium oxide. Mechanical behavior of ceramics. Gauckler eth zürich materials department lab for high performance ceramics überlandstrasse 129 ch 8600. It is difficult to measure the yield strength of ceramics as they tend to fracture before they enter the plastic deformation region i e they are brittle.
