International audience; The aim of this work is to investigate the energetic integral J criterion in generalized plasticity of the F17TNb at isothermal and Thermal Mechanical Fatigue (TMF) tests using a numerical simulation. An optimization of the constitutive law based on mechanical results was carried out using ABAQUS standard solver. Isothermal tests showed that ΔJ evolution is higher at lower temperature (300 °C) and a has a linear dependence at log-log presentation with da/dN at 300 °C. TMF tests simulation showed that Out of Phase (OP) configuration is more damaging than In Phase (IP) tests. A comparison between OP and isothermal tests highlighted the greater value of ΔJ at isothermal tests.
