Is the study of Low Cycle Fatigue (LCF) and cyclic plasticity useful for biomedical metals?

I would like to open a discussion in relation to the following question:

"Is the study of Low Cycle Fatigue (LCF) and cyclic plasticity useful for biomedical metals?"

It appears that there is some level of misunderstanding around this issue. Thus, I would be very interested to find out the views of iMechanica community engineers and researchers working on biomedical metals and applications (i.e. implants) on this.

In your responses, I would appreciate if you could state if you have previous/current experience-involvement in biomedical engineering.

Regards,
