The mechanical properties and fracture behavior of isotropic graphite were investigated after oxidation at 400 or 500°C in air. The bending strength after oxidation was affected significantly by the surface roughness, which was depended on open pore

Thermal stress generated during a thermal shock is closely related to the fracture of ceramics. An attempt has been made to obtain thermal stress in a specimen by numerical calculation. The temperature dependence of thermal conductivity and diffusivi

In the thermal shock test by means of a heated ceramic disk specimen with constant heat flux, temperature distributions in the specimen and time to fracture can be easily measured. Therefore, thermal stress in the ceramics can be estimated without me

A new technique to evaluate the thermal fracture toughness of ceramics was proposed by using the precracked slab specimens. Three kinds of mullite ceramics were used in the experiment. An initial precrack was introduced by the water quenching method,

For evaluation of thermal shock resistance of ceramics by the quenching method, it is important to estimate the thermal stress distribution and history in the specimen. Thermal stress under quenching can not be measured directly in the experiment. Th
