- Ductile materials will withstand large strains before the specimen ruptures.
- Ductile materials often have relatively small Young’s moduli and ultimate stresses.
- Ductile materials exhibit large strains and yielding before they fail.
- Steel and aluminum usually fall in the class of Ductile Materials
- Brittle materials fracture at much lower strains.
- Brittle materials often have relatively large Young’s moduli and ultimate stresses.
- Brittle materials fail suddenly and without much warning.
- Glass and cast iron fall in the class of Brittle Materials.
