Webwell identified by shakedown limit [5] and Dang Van criterion [6]. The crack extension phase has been studied through several fracture mechanics based crack growth models [7]. The growth behaviour of the RCF surface cracks can be classified into two cases: spalling of the rail material due to the coalescence of WebDang Van Criterion . Dang Van assumes that fatigue damage occurs with some grains which are not correctly oriented within the representative volume, which corresponds to some grains going through a plasticity phenomenon whereas the macroscopic stress does not reach elasticity limit and mainly remains in a elastic strain state. He proposes a ...
