Ductile and brittle fracture are two types of fracture that materials can undergo when subjected to external stresses.
Ductile fracture is a type of fracture that occurs in materials that can undergo plastic deformation before breaking. This means that the material can bend or stretch under stress without breaking immediately. Ductile materials, such as metals, can deform significantly before they fracture. When a ductile material undergoes fracture, it often exhibits necking and tearing. Ductile fractures are often characterized by a rough and fibrous surface.
On the other hand, brittle fracture occurs in materials that do not undergo significant plastic deformation before breaking. Brittle materials, such as ceramics, glass, and some polymers, break with little or no plastic deformation. When a brittle material undergoes fracture, it often exhibits a clean and flat surface. Brittle fractures are often characterized by a smooth and shiny surface.
In summary, ductile materials can deform significantly before fracture and exhibit a rough and fibrous surface, while brittle materials break with little or no plastic deformation and exhibit a clean and flat surface.
