Ductile Fracture

Brittle Fracture

Polymers exhibit a variety of behaviors when stress applied

Extensive plastic deformation in vicinity of crack

Always preferred to brittle fracture

Metals typically are ductile when stress is applied

Proceeds slowly

Stable, resists further extension unless further stress is applied

Presence of plastic deformation warns that failure is imminent

More strain energy is required to cause a ductile fracture than a brittle fracture

Occur suddenly and catastrophically without warning

Ceramics are typically brittle when stress is applied
