Animation of the Fracture Process<br />
Initial Fatigue Crack Opening is about 3 microns, a load is<br />
applied gradually until the material reaches the initial <strong>and</strong> then<br />
final fracture toughness strengths followed by unloading to the<br />
final state of deformation<br />
Total experimental time is one minute<br />
The below MOVIE shows the CONCURRENT interaction of macro <strong>and</strong> micro effective<br />
strains due to submicron <strong>and</strong> micron voids growth, interaction, coalescence to form<br />
Micro <strong>and</strong> macro defects (mini-cracks) that eventually define the fracture process zone
