number of cycles to failure ( on a logarithmic scale ) . For obvious reasons curves
of this type have long been used by the design engineer , who after all may not

Thomas ( 28 ) found that at least over a reasonable range the fatigue crack
growth rate range in natural rubber could be expressed in terms of the energy
parameter T by an equation of the form da / dN = AAT " ( 3 . 12 ) where da / dN is
the ...
