18.104.22.168 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.

modulus of selected materials.
