Study Notes
Fracture Mechanics
- Fracture is the separation of material into two or more pieces under the action of stress.
- Ductile fracture is characterized by plastic deformation, mostly seen in metals and polymers.
- Brittle materials exhibit no apparent deformation and are mostly ceramics.
- Ductile materials have a lower yield strength but absorb a greater amount of energy than brittle materials during fracture.
- Fracture toughness is the measurement of the resistance of a material to crack growth.
