Abstrak

In the present work, fatigue crack tip shielding influence is assessed via two full-field optical techniques which are thermoelastic stress analysis and digital image correlation. Two different crack tip field models (CJP and Muskhelishvili) were combined with experimental data from both optical techniques to determine the ΔK<sub>eff</sub>. The crack tip fields were measured on an aluminium alloy (7050-T6) specimen during fatigue crack growth testing for different R-ratios. The obtained results agree well in terms of ΔK<sub>eff</sub> showing a variation in ΔK as the R-ratio changes. Hence, the ability of both techniques and crack tip field models to measure effective fatigue crack driving forces is highlighted.
