In brittle fracture, no apparent plastic deformation takes place before fracture. In ductile fracture, extensive plastic deformation (necking) takes place before fracture.
A ductile fracture is caused by plastic deformation that can be identified by cap and cone appearance of the fracture.
Tungsten typically breaks in a fracture pattern rather than cleavage due to its high strength and resistance to deformation. Fracture surfaces of tungsten are usually rough and irregular, showing signs of ductile deformation.
Brittle objects typically do not undergo plastic deformation due to their inability to sustain significant deformation before fracturing. Instead, brittle materials tend to fracture with minimal or no plastic deformation.

Capable of being hammered out thin, as certain metals; malleable. Can be made into wires.
Force applied to a solid can result in deformation, where the solid changes shape but retains its volume, or in fracture, where the solid breaks apart. The amount of deformation or fracture will depend on the magnitude of the force applied, the properties of the solid material, and the distribution of the force.
Zinc has a brittle fracture at room temperature. This means that when subjected to stress, zinc will break or snap suddenly, without significant deformation. The fracture surfaces are usually flat and exhibit crystalline patterns.
Cobalt's fracture refers to a type of fracture that occurs in metallic cobalt. It is characterized by a clean break in the metal with no deformation or twisting. This type of fracture is common in metals that are hard and brittle.
The fracture of aluminum typically refers to the way the material breaks under stress, which can vary based on its alloy composition, processing history, and environmental conditions. Aluminum can exhibit ductile fracture, characterized by significant plastic deformation before breaking, or brittle fracture, where it breaks suddenly with little deformation, often influenced by factors like temperature and strain rate. Understanding these fracture behaviors is crucial for applications in aerospace, automotive, and construction industries to ensure safety and durability.

A fracture of a material refers to the separation or breaking of the material into two or more pieces due to applied stress or strain that exceeds its strength. This can occur in various forms, such as brittle fracture, where the material breaks without significant deformation, or ductile fracture, which involves considerable deformation before failure. The nature of the fracture can provide insights into the material's properties and the conditions that led to its failure. Understanding fractures is crucial in fields like engineering, materials science, and structural design to prevent catastrophic failures.
