Document Summary
Representing the behavior of materials on a stress strain diagram. Well a stress strain diagram is a graph that models the behavior of a specimen. This graph is constructed with stress on the y axis and strain on the x axis. It helps to illustrate a relationship between the two. This is an example of one of the diagrams. As you can see, there are very distinct sections on this graph that we can describe: elastic region, which is conducive of elastic behaviour. Any deformation will revert to its original shape when unloaded yielding region. This region marks how a material resists plastic deformation before reaching its ultimate tensile strength. Here, the cross-sectional area begins to decrease in a localized region of the specimen. Def: materials that can be subjected to large strains before it ruptures is called a ductile material. Def: materials that exhibit little or no yielding before failure or referral to as brittle materials.
