3. Local approach to fracture mechanics

3.1 Principle of the local approach to fracture mechanics

The local approach [6] consists in comparing the state of local stresses and strains in a part, particularly at the end of a crack, with a local criterion that differs according to the fracture mechanism: cleavage or ductile-facies fracture by initiation, growth and coalescence of cavities (see [M 4 165] ). This makes it possible to predict the fracture of a part, or the behavior of a cracked part, by overcoming the effects of the greater...
