Examples of brittle materials include glass, cast iron, high carbon. Introduction to mechanics of materials and theory of stressstrain state 5. Elastic materials hookes law a material is said to be elastic if it returns to its original, unloaded dimensions when load is removed. Also known as unit deformation, strain is the ratio of the change in length caused by the applied force, to the original length. This operation allows one to evaluate which material is best suited for the application. Consider the bar in figure 1 subjected to a simple tension loading f.
