Breviary Technical Ceramics



 Tensile strength

The low tensile strength, which can often be 20 % less than the bending strength, and the tendency to brittle breakage (see Figure 80) of ceramics require that tensile stress should be avoided or minimised, or at least that the stress distribution should be calculated as accurately as possible. This does not entirely exclude the possibility that, for instance, components such as open-air insulators used for high voltage power transmission can be successfully, if inappropriately for ceramics, used under conditions of tensile stress.
