5.3.4 Elastic Properties

5.3.4.1 Elastic modulus

The elastic modulus E [GPa] of almost all oxide and non-oxide ceramics is consistently higher than that of steel. This results in an elastic deformation of only about 50 to 70 % of what is found in steel components. The high stiffness implies, however, that forces experienced by bonded ceramic/metal constructions must primarily be taken up by the ceramic material.

Test procedures for determining the modulus of elasticity are defined in DIN EN 843-2 and DIN EN 60 672-2.
