2. Fundamentals of fracture mechanics

2.1 A reminder of linear elastic fracture mechanics (LERM)

The aim of this paragraph is to provide a brief reminder of linear elastic fracture mechanics (LERM), and in particular to introduce the notion of energy restitution rate, which will be widely used later, but there are a large number of more specialized works that can supplement this brief account
