Q: Is fracture the separation of an object or material into two or more pieces under the action of stress? ¶
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? ¶
Q: Is fracture more likely to occur? ¶
Q: Is fracture : void formation? ¶
A: Yes, and void coalescence , crack propagation, and failure, often resulting in a cup-and-cone shaped failure surface.
