... as investigated by Arif et al. [ 2 , 3 ]. Therefore, it is very desirable to identify critical process parameters and die design features so as to predict their susceptibility to failure due to cyclic fatigue. Finite element simulation is an efficient tool for analysis of forming processes and tool loading...

This process truncated real loadings in the same way that actual service loads would have been truncated in the aircraft. The resulting truncated load history was then used as input to a computer program. This program...
