Ceramics tend to be weak in tension but strong in compression.
Compressive strength of ceramic s.
Material specific gravity sg coefficient of linear expansion α m m k maximum safe operating temperature o c.
Usually ceramic strength is tested using a four point bend test.
Ceramics have compressive strengths about ten times higher than their tensile strength.
Ceramic materials offer a number of benefits in a variety of applications.
4 2 generally resistance to compression is the measure of the greatest strength of a monolithic advanced ceramic.
The tensile strength of ceramics and glasses is low because the existing flaws internal or surface cracks act as stress concentrators.
Ideally ceramics should be compressively stressed in use although engineering applications may frequently introduce tensile stresses in the component.
The properties and the processing of ceramics are largely affected by their grain sizes and shapes and characteristics such as density hardness mechanical strength and optical properties strongly correlate with the microstructure of the sintered piece.
For a metal the compressive strength is near that of the tensile strength while for a ceramic the compressive strength may be 10 times the tensile strength.
