Digital image correlation measurement of near-tip fatigue crack displacement fields: constant amplitude loading and load history effects

ABSTRACT Recent work by de Matos and colleagues employed digital image correlation to measure near tip displacement fields for fatigue cracks in 6082 T6 aluminium alloy. The main focus of this work was to directly measure fatigue crack closure, but the measurements can also be used to examine condit...
