理解断裂的另一种方法不是研究应力场，而是研究能量流入和流出容易断裂的物体。在这一章中，将考虑断裂所需的能量，并建立能量流和裂纹尖端应力之间的联系。这种联系也为确定应力强度因子提供了一个强有力的工具。请注意，除非特别注明，无论材料是线弹性还是非线性弹性，断裂的能量方法都是相同的。
An alternative approach to understanding fracture is to look not to the stress fields but to the flow of energy into and out of an object that is susceptible to fracture. In this chapter the energy required for fracture will be considered and the connection between the energy flows and the crack tip stresses will be made. This connection also provides a powerful tool for the determination of stress intensity factors. Note that, except where noted, the energy approach to fracture is the same whether the material is linear or nonlinearly elastic.
