dc.description.abstract	Fatigue simulations on single crystal bcc iron have been carried out by using Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) package. Finnis-Sinclair potential suitable for bcc iron has been chosen to desc ibe the interatomic interactions. Fatigue simulation was carried out at 573 K by employing fully reversed, total strain controlled cycling at various strain amplitudes in the range of ± 7% to ± 10%. From the simulation results, effect of cyclic strain amplitude on cyclic stress response and cyclic stress-strain behaviour has been determined. The development of fatigue damage with successive number of cycles using Atom Eye software has been examined.	en_US
