Afrl-rx-wp-tp-2012-0389 Microstructure-sensitive Hcf and Vhcf Simulations ( Preprint )

This paper provides some background and historical review of how microstructure-sensitive finite element simulations can play a role in understanding effects of stress amplitude, R-ratio, and microstructure on fatigue crack formation and early growth at notches, including pores and non-metallic inclusions for Ti alloys and Ni-base superalloys. Fatigue… CONTINUE READING
