Fracture FAQs:

Q: Is fracture the separation of an object or material into two or more pieces under the action of stress?

A: Yes.

Q: Is fracture less common than other types of failure?

A: Yes, and the impacts to life and property can be more severe.

Q: Is fracture : introduction of a flaw either before or after the material is put in service?

A: Yes, and slow and stable crack propagation under recurring loading, and sudden rapid failure when the crack reaches critical crack length based on the conditions defined by fracture mechanics.

Q: Is fracture the more common fracture mode?

A: Yes.

Q: Is fracture more likely to occur?

A: Yes.

Q: Is fracture : void formation?

A: Yes, and void coalescence , crack propagation, and failure, often resulting in a cup-and-cone shaped failure surface.
