Meaning of Ductile and Brittle Fracture
Meaning of Ductile and Brittle FractureThe terms ductile and brittle are commonly taken as self-descriptive, but care should be taken in using them. They are used to indicate the general plasticity at fracture, relying on such quantities as the elongation at fracture (ductility) and the presence of necking to indicate whether the material is ductile or brittle. A difficulty here is to decide how much ductility is required to place the material in a ductile class; there is no common value to be used. More pertinent to our interests is that the terms ductile and brittle are used to distinguish ductile and brittle fracture, both the macroscopic and the microscopic aspects. As is discussed in
