Stress Strain Graph Ceramics

Plot the diagram and determine the modulus of elasticity.

Stress strain graph ceramics.

1 metals al alloy stress strain curve. 7 18 callister rethwisch. Three point bending apparatus used determine stress strain behavior. 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 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. There are various sections on the stress and strain curve that describe different behaviour of a ductile material depending on the amount of stress induced. It was found that they behaved as elastic materials. The stress strain curve is a graph that shows the change in stress as strain increases.

Data taken from a stress strain test for a ceramic are given in the table. The electric strain gauge was used to study the deformation of several types of ceramic materials under stress. It is a widely used reference graph for metals in material science and manufacturing. The curve is linear between the origin and the first point.

With a very short elastic region but highly capable of supporting huge stresses. And finally analogous to ceramics are the stiff fibers and rigid plastics.
