Abstract:	In this paper, a new FE crack propagation method called SMART was studied in order to make a proper validation for further probable implementation. The target application field is the rail-way contact phenomena where the thermal RCF problem is required to be investigated from the crack propagation point of view on a more efficient way. Experimental test was performed previously by Peixoto to validate a sub-surface crack propagation model. The validation was performed on a CTS specimen with mixed-mode loading conditions, evaluating the crack propagation angle. Correspondingly, we used the same test apparatus but we calculated with a different method. During the analysis, Paris’ law was used to model the constant propagation phase of the crack. The comparison of the previous and current results indicate that the new method performs well and shows similar values as the experimental evaluation and other FE methods. However, some of its’ assumption entraps the tool from being able to analyse certainly complicated environments but the testing on a bit higher level can be started.
