with that for stress intensity factor range Î”K, was used to develop
a fatigue propagation life model, after substituting parameters of material
constants. The model was then employed in creating simulation software
which can be used at any time to generate data, make design consideration
and predict response to variable loading. This became useful in predicting
the life of metal from the point of crack initiation; investigate behaviour
to changes in crack sizes and also determine adequate damage tolerance
for the metal.]]>Anderson, T.L.,1995Ashby, M.F. and D.R.H. Jones,2005Benham, P.P., R.J. Crawford and C.G. Armstrong,1996Chau, K.T. and S.L.
