  The accumulated entropy is used to evaluate the initiation of crack in flat
notched specimen made of stainless steel 304. Two notch radii have been studied
to capture the thermography of crack initiation and measure accumulated heat
dissipation. It has been observed that under pull-push loading with an R-ratio
of -1, the accumulated entropy for crack initiation and crack length's growth
up to a specific number, Fracture Fatigue Entropy remains nearly constant.
Anaclastic deformation dissipation has been taken into account and a
mathematical model based on Kelvin-Voigt type element has been discussed. The
effect of anelastic deformation has been studied in terms of temperature
evolution at the beginning of the test.
