What is ductility? :: Anton Paar Wiki

The ductility and brittleness depend on the special cohesive characteristics of the sample. The behavior depends on the temperature. For example, bitumen shows a brittle fracture at low temperatures. To determine this, a special Fraass breaking point bending test (EN 12593) is used. At room temperature, a ductile fracture occurs.
