Stress Strain Curve For Ceramics

In engineering and materials science a stress strain curve for a material gives the relationship between stress and strain it is obtained by gradually applying load to a test coupon and measuring the deformation from which the stress and strain can be determined see tensile testing these curves reveal many of the properties of a material such as the young s modulus the yield strength.

The electric strain gauge was used to study the deformation of several types of ceramic materials under stress. Stress strain curves for two brittle materials. 2 stress strain curve for ceramics.

Quasi ductile ceramics 523 indentation stress strain po a r data are plotted in fig. 1 metals al alloy stress strain curve. Elastomers are the ones that strains more w a lower stress. With a very short elastic region but highly capable of supporting huge stresses.

Indentation stress strain curves for base glass and glass ceramics heat treated at specified temperatures for 4 h. It was found that they behaved as elastic materials. 5 for each of the glass ceramic. And finally analogous to ceramics are the stiff fibers and rigid plastics.
