Physical Property Measurement: Types of Fracture

Fracture is simply crack propagation. Force has to be exerted to initiate a crack, then energy has to be supplied to propagate it. This is the energy that goes into breaking the bonds within the material in order to generate new surfaces. 

There are three ways a crack can propagate within a material. All structural failures are the result of material failure in one of these three modes.
