In situ SEM-DIC and EBSD measurements on cold-worked AA-5052 show crack arrest coincides with divergence of elastic and elastoplastic energy release rates as the crack-tip process zone expands beyond grain size.

In situ elucidation of mechanisms governing crack transition to plasticity arrest
In situ SEM-DIC and EBSD measurements on cold-worked AA-5052 show crack arrest coincides with divergence of elastic and elastoplastic energy release rates as the crack-tip process zone expands beyond grain size.
