Finite element modeling of the coupling between thermal dissipation and fish-eye crack growth in very high cycle fatigue regime

摘要：

　　The aim of the paper is to model the thermal dissipation associated to a fish-eye crack growth during an ultrasonic fatigue testing.We use a Paris-Hertzberg crack growth model to simulate the evolution of the crack and a perfectly elastic-plastic constitutive law to model the plastic dissipation per cycle.A finite element analysis is used to compute the evolution of the temperature field during the crack propagation.Numerical results are presented and they agree well with experimental results.
