Models allowing the prediction of the failure of structures by crack propagation were first introduced in the 50s using linear fracture mechanics whose principles were first proposed by Griffith (1920). This approach was extended to non linear cases (plasticity and viscoplasticity) in the 70s based on the work of Rice (J or C* integrals)
