Stress strain curve for ceramics.

It was found that they behaved as elastic materials. Quasi ductile ceramics 523 indentation stress strain po a r data are plotted in fig. The electric strain gauge was used to study the deformation of several types of ceramic materials under stress. For brittle ceramics a three point bending apparatus shown in the figure below is used determine the stress strain behavior and the measurement results are used to calculate an equivalent modulus of elasticity.

With a very short elastic region but highly capable of supporting huge stresses. 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. And finally analogous to ceramics are the stiff fibers and rigid plastics. 1 metals al alloy stress strain curve.

2 stress strain curve for ceramics. 5 for each of the glass ceramic. The hard fired materials exhibit straight line deformation to failure while the softer fired have a proportional elastic limit beyond which the stress strain curve deviates. Indentation stress strain curves for base glass and glass ceramics heat treated at specified temperatures for 4 h.
