Compression Test On Ceramic

4 2 generally resistance to compression is the measure of the greatest strength of a monolithic advanced ceramic.

Compression test on ceramic.

Any testing standard will do e g. Ae cumulative event counts during compression for a dumb bell specimen of alumina. Astm din iso etc. Some materials such as a pet bottle distort during a compression test and are measured by the degree of distortion whereas other materials such as ceramics fracture produce a definitive compressive strength value.

Uniaxial compression is a well known experimental procedure to characterize the mechanical properties of metals polymers and ceramics by establishing the relationship between the uniaxial stress state prescribed by the loading condition and the induced triaxial strain state for an ideal uniaxial compression test a uniform stress state is expected to arise within the. Ideally ceramics should be compressively stressed in use although engineering applications may frequently introduce tensile stresses in the component. There is a need to know accurately the strength of brittle materials in compression both to distinguish between competing statistical micromechanical theories of strength and to provide data necessary for engineering designs for the optimum use of these materials as load bearing elements.
