CRACK MECHANICS

Une fissure instable est une crique qui craque!

All the previous chapters have treated the behaviour of a volume element by considering it as a continuous medium, represented by its state variables. The theory of cracking phenomena or fracture mechanics describes the behaviour of solids or structures with macroscopic geometric discontinuities at the scale of the structure. These discontinuities are line discontinuities in two-dimensional media (such as plates and shells) and surface discontinuities in three-dimensional media. The theory of damage can be used to predict the onset of a macroscopic crack. The theory of cracking phenomena, on the other hand, can be used to predict the evolution of the crack up to a complete failure ...
