Material failure Stress calculation is practical for engineering design, since every material has a limit, where deformations become permanent, in the sense that they do not vanish when a component is unloaded. We say, that plasticity has occurred contrary to elastic material behavior, for which deformations are not permanent. For most design applications, it is undesirable to have plastic deformations, so this limit should not be exceeded (more about this in your course on mechanical elements/technical design). We denote the stress, where the elastic regime ends, the yield stress and denote it. Once plasticity is encountered, the stress-strain curve will no longer be linear, but further loads may still be applied until the ultimate stress is reached. When this stress is exceeded, fracture occurs and the material fails. However, once the yield limit is exceeded, two types of material behavior are common and will be considered in the following. Materials may either be ductile, meaning that they possess a certain fracture-toughness in impact tests, and deform significantly in the plastic regime, or brittle, where impact loads easily cause fracture, and very little plastic deformation occurs prior to fracture.
